Bug Description
Binary package hint: xserver-
Testing out the daily image from September 12 2009, the live cd is not booting up to X. It is falling back to failsafe graphics mode.
This happens because the 'nv' driver has it's pci_match_id section set to match any nvidia device and does it's logic to abort in the probe routine. This approach causes troubles because the X server has already claimed the device by the time it's been matched, and so it's not able to free it after the probe routine fails. This prevents any fallback drivers (such as vesa or fbdev) from claiming the device.
This problem has been known to manifest on mostly newer NVIDIA hardware such as the 9400M in the Studio XPS 1340, or the Zotac ION.

Here's my failsafe .tar. It's far more informative than any of that ubuntu-bug stuff (since the ubuntu-bug stuff was done when I booted with VESA forcefully)
