           Summary: x1300 kms failure
           Product: xorg
           Version: 7.4
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: yoshi314 at gmail.com
         QAContact: xorg-team at lists.x.org


there are multiple problems rolled into one. 

to sum it up:

booting 2.6.32.* and 2.6.33 kernel with radeon.modeset=1 causes it to stall for
~33 seconds. finally kms kicks in . on 2.3.32 it set an incorrect mode (too
high refresh rate), on 2.6.33 it works correctly. 

2.6.31 was the last properly working kernel where kms had no delays.

however, i found in dmesg that delay was (probably) caused by missing firmware,
namely radeon/R520_cp.bin . 

i included that in my initrd and when booting with KMS display goes entirely
white. and it seems to lock up completely.

lspci:
05:00.0 VGA compatible controller: ATI Technologies Inc RV515 PRO [Radeon
X1300/X1550 Series]
05:00.1 Display controller: ATI Technologies Inc RV515 PRO [Radeon X1300/X1550
Series] (Secondary)

right now i'm using daewoo cmc-1427x old crt display. maybe that's the source
of the problem?

i'll provide necessary logs, if needed.
