Can anyone think of anything we might have done between 2.6.24 and
2.6.25 to break the nvidia driver's boot-command-line handling?

Thanks.

Can you give more details what this means? Does this gives you another graphics
mode or the machine boot in text mode? I assume the latter.
I do not have configuration to reproduce this  (I do not have any GeForce
card and I do not use grub).

Another thing is that the 317 may be not right setting. I googled about grub
configuration and it should be either

vga=0x317

or 

vga=791

Please confirm if these new settings gives you the error as well.

Regards,
Krzysztof
