I also confirmed that adding "nouveau.modeset=0" to the kernel's boot options is sufficient.
Ant, the nvidia-installer will work over SSH fine.
Edit: I re-read Roman's post and saw that he is using 2.6.32-5. I'm sure the package he installed does something to disable Nouveau, since Nouveau is indeed included in Debian's 2.6.32-5 kernel.
Hmmm... it might be best to compile own kernel without Nouveau (and other unnecessary modules).
