After a bit of testing I've found the problem:

kernel-2.6.29.1-70.fc11.x86_64 = video freezes up after a few seconds

kernel-2.6.29.1-68.fc11.x86_64 = OK
kernel-2.6.29-0.258.2.3.rc8.git2.fc11.x86_64 = OK

Therefore the solution is just to change grub.conf to boot off 
kernel-2.6.29.1-68.fc11.x86_64 for now.

So far running Fedora 11 beta using ext4 is lightning fast and stable - 
thanks to all the developers it's look great!
