I think I know what's the problem with my X server crashes already.

Under the default Fedora 11 installation, the kernel module (driver) nouveau is loaded for my PCI Express x16 nvidia chipset graphics card.

However, after compiling Xen pv-ops dom 0 kernel 2.6.30 rc3 and 2.6.31 rc6, the nouveau driver for my graphics card is no longer there.

Do I have to update the X server and/or the C library?
