I promise you it's an Apollo Pro 133A and it identifies with 0605, not with 0691.
This is the mobo I have: http://www.motherboard.cz/mb/asus/CUV4X.htm

It doesn't, without adding that line my computer reboots when running OpenGL apps.
I have tried maybe 5 times to recompile the kernel without it, same result every time.

Is there anything I can do to confirm, check why I need this or something? I have tried checking
the syslogs after the computer reboots but I never found anything related to it.
I'd prefer not to run too many tests though, since sometimes my drives get corrupted.

I just switched back to CURRENT to check how it would behave when I added these lines. When I
load agp.ko now I get this extra output:
on pci0 pcib1: could not get PCI interrupt routing table for \\_SB_.PCI0.AGP_ - AE_NOT_FOUND

and I had to set the AGP rate to 0, otherwise the machine will hang randomly (not OpenGL related
this time since it will hang even though I haven't run any OpenGL apps).
I have tried not loading agp.ko and using nvidias agp (by enabling in XF86Config), but that
yields the same result as agp_via.c without the added ID.


Now this is very strange, I did a search and indeed, the id is 0691. I was unable to find the
page that said that it was 0605 =(.
Now I'm positive I have a CUV4X mobo which has a 694X AGP chipset. Do you have any hints to how
I can debug this, because it works with id 0605 and it doesn't work without it, which does not
make any sense I guess.
