Do upgrade your BIOS to the latest version. These things have broken
ACPI implementation that most likely is the reason for the overheat.

There may be a bug somewhere (especially if you are using fglrx driver),
but that should not matter - a properly working system may run at 100%
load forever, and will not overheat.

Ubuntu is NOT Debian. They replace large parts of Debian with software
of their own, that is usually is more unstable, and has different set of
bugs. For this reason we (Debian guys) can only give you general advise,
but pinpointing specific bugs is not really possible.
And I still strongly encourage you to upgrade to 2.6.21 (it is available
in Debian Unstable), because it fixes a lot of problems with HP laptops.
WARNING: Do NOT compile kernel on said laptop. Compiling is very
CPU-intensive task, and may damage your hardware, if cooling does not
properly work.
Some HP laptops have an option in the BIOS to force the fans on (at
slowest speed), when using AC power. But this may not be enough to cool
the CPU under heavy load. Better than nothing, though.
You may need _both_ the kernel and the latest BIOS to get going. You
mentioned that you have XP installed - use it to update the BIOS via HP
tools.
