I've tried Knoppux with three laptops this evening:

X-org intel driver: OK
X-org sis driver: OK
X-org vesa driver: OK

This last is a really old laptop with a SiS chipset but when I boot without xmodule=vesa it starts the LXDE desktop, the bottom panel appears and then disappears and X exits. Guess this isn't a memory leak because Knoppix just restarts the X server again, over and over again, in exactly the way it didn't for FlameWeasel. Odd thing is, even with X restarting and restarting I can still use ctrl+alt+F1.

I could suggest a few things to try that might shed some light on the problem but since condescension is out I'll have to take a wild guess ....

You have a hard drive installation. You have a persistent store. When you installed Knoppix 6.4.4. you kept your old persistent store that you've been using for years. Thus you've carried forward the same xorg.conf file from release to release. It has got some retro stuff in there that it should not.

Try moving your xorg.conf to one side and copying over the original from the 6.4.4 distribution. Reboot and see if that makes a difference.
