I had the same problem going from 2.6.23-gentoo-r9 to 2.6.24-gentoo-r3 using 
the legacy nvida 96.43.01 driver. The masked 96,43.05 driver works on the new 
kernel,but it is unstable on my old Geforce MX 440 card.

What I did discover was a nasty hack to get the old driver to recognise the 
new kernel version:

# ln -s  /usr/src/linux/include/asm-x86 /usr/src/linux/include/asm-i386

( This assumes that /usr/src/linux points to the new kernel 2.6.24-gentoo-r3)

It looks like the kernel devs are trying to update references to the include
asm files and the nvidia devs are yet to catch up. Maybe one day nvidia will 
release its driver specs and save itself a lot of trouble and money building 
catchup linux drivers. Maybe hell will also freeze over on that day.

Hope this helps.
