Comment 8 for bug 533642

Looks like accidental blacklisting:

$ ls /etc/modprobe.d
blacklist-ath_pci.conf blacklist-oss.conf libpisock9.conf oss-compat.conf
blacklist.conf blacklist-watchdog.conf nvidia-graphics-drivers.conf
blacklist-firewire.conf dkms.conf nvidia-kernel-nkc.conf
blacklist-framebuffer.conf ibm_acpi.modprobe.dpkg-bak nvidia-kernel-nkc.dpkg-old

$ grep nouveau /etc/modprobe.d/*
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist nouveau
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist lbm-nouveau

This is via /usr/lib/nvidia-current/modprobe.conf from nvidia-current.

I had removed the package on Sun Mar 7 22:53:20 2010 +0100, but then reinstalled on Mon Mar 8 21:03:30 2010 +0100.

Odd - I've thought I had no installed it again. I will try now again.
