Public bug reported:
System in question (Thinkpad T60 / Mobility Radeon X1400) has been
upgraded from Ubuntu 9.10.
When booting from Grub, the kernel command line will be displayed for a
short time (in text mode), and then maybe 1/5th of the screen will be
filled with graphics garbage. At this point, the only way out is to
switch off the system. In rare cases, the CMOS checksum is invalid after
powering back on.
Workaround: Specify "nosplash noquiet" on the kernel command line (just
"nosplash" will not do).
