The change between Ubuntu 9.10 and 10.04 most likely to have caused this
was enabling KMS by default on your card.  You can disable KMS for one
boot by adding “nomodeset” on the kernel commandline, after “quiet
splash”.

To edit the kernel command line you need to press ‘e’ at the GRUB menu.
If the GRUB menu doesn't normally appear for you (by default it only
appears if you've got a dual-boot setup) you can make it appear by
holding down “shift” during the early boot process, just after the BIOS
boot screen.

If booting with “nomodeset” fixes the screen problem, it would be good
if you could attach the /var/log/Xorg.0.log file.

It would also be good if you could boot with the FW900 monitor attached,
adding “drm.debug=0x04” instead of “nomodeset” to the kernel
commandline.  That will make the kernel print out lots of debugging
information.  Since the screen won't be usable, you'll have to reboot.
The debugging messages will be saved in /var/log/messages, which you
should attach to the bug.  There is sometimes some sensitive information
in /var/log/messages, so I'm marking this bug as private until we've
inspected it and extracted the debugging logs.
