Re: Compiling nouveau open source nvidia graphics card drivers for Xen paravirt-operations domain 0 kernel

["Mr. Teo En Ming (Zhang Enming)" <enming.teo@asiasoftsea.net>]

Dear Pasi,

I have nouveau driver on my stock/default Fedora 11 kernel that does not 
depend on ttm.

lsmod | grep ttm shows up nothing.
