Here's what I get with 2.4.12-ac3-lowlatency (non-fixed X11 driver):

And here's 2.4.16-lowlatency (non-fixed X11 driver):

Here's 2.4.16-lowlatency with some small patches (fixed X11 driver):

Here's 2.4.17-ide-rmap-O1-minill (fixed X11 driver):

So, only usable kernel is still 2.4.12-ac3 with fixed X11 driver.
