Lauri, it could also be that your problem is a different one. At least some lockups seems to be highly related to sky2 and network traffic.
Anyway, since the 3 days I run linux-image-2.6.20-13-generic version 2.6.20-13.21 I haven't encountered any new lockups. Maybe the problem is already fixed in that new kernel? Do other people still have lockups with the latest kernel version? If yes, then hopefully the next Ubuntu kernel will fix them. In the changelog [1] of Ben Collin's git are several updates for the sky2 driver.
