I just installed 12.04 beta2 and the pci=bios solution works flawlessly under 32bit.
After the initial installation you edit the grub settings and add the pci=bios option, then after update-grub you can install the nvidia drivers.
In a terminal type:
sudo gedit /etc/default/grub
look whether there already is an existing GRUB_CMDLINE_LINUX="" and change it to GRUB_CMDLINE_LINUX="pci=bios", if it doesn't exist then just add the GRUB_CMDLINE_LINUX="pci=bios" to the file and save it.
type sudo update-grub, install the Nvidia drivers and restart your computer - it should work.
