Xorg.0.log of setup after resume

SW: ubuntu 8.04, pool/main/x/xorg/xorg_7.3+10ubuntu10.1_i386.deb
HW:
00:0f.0 VGA compatible controller: ATI Technologies Inc 3D Rage Pro 215GP (rev 5c)
01:00.0 VGA compatible controller: 3Dfx Interactive, Inc. Voodoo 3 (rev 01)

tdfx is set as :0.0
ati as :0.1

All works fine until I suspend (to ram) and resume, then X seems frozen, when I kill it with sysrq-k, only tdfx works, so a reboot is needed, to get ati card working.

I think this is very possibly related to these lines from log (-working +non-working):
-(II) Primary Device is: PCI 01:00:0
+(II) Primary Device is: PCI 00:0f:0
...
 (II) TDFX(0): Softbooting the board (through the int10 interface).
-(II) TDFX(0): Primary V_BIOS segment is: 0xc000
+(II) Attempted to read BIOS 64KB from /sys/bus/pci/devices/0000:01:00.0/rom: got 40KB

Xorg.0.log of a working tdfx+ati setup
Comment 2 Domen Puncer 2008-06-07 05:19:41 UTC 
I tried setting BIOS to initialize PCI card (ati) first, and there was progress:
Right after resume, the ati-screen worked, unfortunately the tdfx screen was just blank.
But after restarting Xorg, both worked fine.

So my possibly flawed conclusions are:
- Primary vs. secondary card might be a BIOS issue (not setting them up right when resuming).
- Xorg doesn't bring up secondary (bios-wise; the one not on 0xc000) card after resume.

Is there anything I can try? More info I can provide?
Comment 3 Matt Turner 2010-12-03 12:24:01 UTC 
Is this still a problem?
Comment 4 Domen Puncer 2010-12-03 14:09:44 UTC 
Well... no, since I no longer have that setup.

Mass closure: This bug has been untouched for more than six years, and is not
obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
