So, no thanks to Nvidia support, i was able to finally crack the problem i was having with getting my 9800GT card working under Jaunty Jackalope (9.10). The secret? Read the damn X.org wiki. More here

So, i’ll admit that this is also a delightfully cryptic message. A bit of sleuthing turns out that the problem is with the kernel configuration, which means that you’ll need to modify the grub configuration. (Or you can interrupt grub, and manually edit the “/boot/vmlinuz … ” line to add “vmalloc=256MB”) If you do modify the /boot/grub/menu.lst file, be sure to run grub-update to install it.
