Hi Ben,

Thanks for all the work on the patches, it's definately an improvement - 
prior to these latest set of patches I couldn't even start X reliably since 
going to modular X.  I'm using a sharp MM20 notebook with a radeon mobility 
M6 LY, 16Mb chip, gentoo 7.0-r1 xorg, and dri from CVS (with your 
radeon-memmap-drm-3 patch). radeon driver is 6.5.7.3 ebuild with your patch 
added.  DRI still hangs the machine, although it seems to get all the way 
through initialization with no problems (the logs look clean). VT switching 
as well cycling through resolutions work, but there is about a 7 second 
delay during which the machine isn't responsive to keyboard/mouse.  
Otherwise no freezes, high cpu utilization or lockups, suspend/resume seems 
fine, etc.

just out of curiousity, do you know how to specify the monitor dpi if it's 
not detected correctly? i'd swear that windows was doing 96x96 (not 
installed anymore) but it's always 75x75 with xorg.  it appears that the 
driver can't get it from DDC/EDID, the user space read_edid utility couldn't 
retrieve it either...  any thoughts?

thanks,
-brian
