Sorry for the big delay, but only today I was allowed to reboot one of the 
machines. Sorry again for not being of any help: I could not boot 2.4.20-pre5! 
It stopped inside the AGPGART code (part of this is taken from a clean 2.4.19 
boot because someone had to read it from screen and tell me by phone):

Normally it would print the aperture size, but this did not happen, the machine 
simply froze. However, it took some time for the spurious interrupt to appear.

I would be glad to test your patches with 2.4.19, but as I understand I would 
have to incorporate the NAPI changes as well? Would it be possible to create a 
patch for 2.4.19?

Ciao,
