Xorg configuration

I sent the following to questions at freebsd.org and got no replies.  I'm
not sure if this is the right list to raise these issues or whether
there is a more specialized list, or whether I should take this up with
KDE once I get that running again.  So I apologize beforehand if this is
the wrong place and I'd be grateful if someone would be kind enough to
redirect me to the proper venue.

I'm trying to configure X on a Dell 4300S which dual boots FreeBSD
6.1-RELEASE and Windows XP.  After I ran Xorg -configure and added the
HorizSync and VertRefresh options for the Gateway EV500 Monitor (taken
directly from the vendor page at
http://support.gateway.com/s/MONITOR/Z00635/z0063510.shtml--yes, it's
almost a relic :) and Depth 24, Modes "1024x768", just as in the
Handbook, I was able to run X but I got one error and a few warnings. In
a previous round with this hardware (but with 6.0-RELEASE), I had gone
as far as installing KDE with a very similar xorg.conf and with similar
errors/warnings IIRC.  Since KDE would take several minutes to start
(*noticeably* longer than XP, like 5-10 mins), I want to make sure that
these errors are not the underlying cause for the bad performance.

The first warning (together with some surrounding messages) is:

(**) R128(0): Using external CRT for display
(II) R128(0): Primary Display == Type 3
(WW) R128(0): Can't determine panel dimensions, and none specified.
     Disabling programming of FP registers.
(II) R128(0): PLL parameters: rf=2950 rd=65 min=12500 max=35000; xclk=13000
(II) Loading sub module "ddc"

The error and the other warnings are as follows:

(II) Loading sub module "i2c"
(II) LoadModule: "i2c"
(II) Loading /usr/X11R6/lib/modules/libi2c.so
(II) Module i2c: vendor="X.Org Foundation"
     compiled for 6.9.0, module version = 1.2.0
     ABI class: X.Org Video Driver, version 0.8
(II) R128(0): I2C bus "DDC" initialized.
(II) R128(0): I2C device "DDC:ddc2" registered at address 0xA0.
(II) R128(0): I2C device "DDC:ddc2" removed.
(EE) R128(0): No DFP detected
(WW) R128(0): config file hsync range 30-69kHz not within DDC hsync ranges.
(WW) R128(0): config file vrefresh range 50-110Hz not within DDC
vrefresh ranges.
(II) R128(0): Monitor0: Using hsync range of 30.00-69.00 kHz
(II) R128(0): Monitor0: Using vrefresh range of 50.00-110.00 Hz
(II) R128(0): Clock range:  12.50 to 350.00 MHz

 From my research, DFP (and FP) refers to Digital Flat Panel.  Since
according to the r128 man page, Option "Display" defaults to "FP", I
added Option "Display" "CRT", but it didn't make any difference.

So, is there any harm to the WW's and EE above?  Could they be the cause
for the bad KDE performance?

One other doubt:  at times, if I run say, xdm, the initial screen is a
garbled up version of the XP logon screen and it lingers for a while,
and at least once, the PC got locked up, the Ctrl-Alt-Fx combinations
couldn't switch to other VTs (as I had seen with KDE during the long
startup) nor did Ctrl-Alt-Bksp kill the X server and the only thing that
stopped it was a dreaded Ctrl-Alt-Del.  Since I haven't really used X
before, I don't know if this is normal or not.
