Anyone else seen VM related oops on 2.4.18?

Hello.

Yes:(
I've seen that oops 24/7 after installing a new video card Radeon 7500 AGP.
Before I had PCI video card.
When DRI is enabled, the whole box hangs after ~10 minutes of using OpenGL, and if DRI disabled and radeon.o is unloaded, I have a vm-related Oopses. Exactly the same: invalid operand in __free_pages_ok(). I still have a lot of them in my system log, but I am afraid I don't have the relevant System.map for ksymoops'ing them.
I tried to switch to -ac tree and what I get is just about the same Oops:

BUT: Andrea vm patches seems to cure that!
I am only two days with them, so everything is still possible, but before it used to Oops just about every half an hour.
So thousands of thanks goes to Andrea:)

Btw, I've seen exactly the same reports in DRI
mailing lists and they were reported with different video cards, but the similar thing was that all the reporters has an AMD 751 Irongate as host bridge.
I also have it.
What is your north bridge?
This really seems strange for me that video card
or the host bridge causes vm to oops, but who knows...
Anyway, it is definitely not a nvidia drivers related:(

If anyone wants me to reproduce and ksymoops this Oops, feel free to ask. I am ready to do just about everything to get this problem fixed, else I just can't use my new cool Radeon...

You can use dri with your 7500? Same processor as 8500 cards? If so, which X sources are you using?

I bought an 8500 Evil Master II specifically because I saw Radeon support in the kernel and X source. Much to my chagrin, I can't use dri because the source (4.2.0) says dri is not yet implimented for that processor.
