The patch that I linked to went into 2.6.16-rc5-bk12 (yesterday's), so
yeah, that's probably too old. ;)
Even with this, one of the boards I have (RS482) is reporting periodic
APIC errors, though this doesn't seem to affect the machine's stability.

Knoppix's kernel is probably much too old. You might want to try one of
the livecd's from ubuntu's beta release and see how things work.

The X300 is now supported by the open source 'radeon' driver:
http://ftp.x.org/pub/X11R7.0/doc/html/radeon.4.html
You'll need xorg 6.9 or 7.0 though, and you'll only get 2D support.
Fortunately, it looks like basic 3d support is being worked on for the
X?00 seriers cards. I've had some good luck with "regular" 2d support and
my ATI X800XL, and the chipset built-in RS48x with this driver.

AMD's new dual-core turion line (supporting DDR2) is being launched soon.
I'm pretty sure you'll see nvidia nforce 61x0 style laptops with it, since
AMD has been seen demoing turion kits with "similar" configurations. It's
always hard to tell what you'll see on the market when things finally come
to light..
later,
