That is true, I even compiled kernel back to 2.6.19, and used absolutly
minimal driver configuration (ahci + vga console + keyboard).

(Yes, screen here doesn't came back to life without nvidia propertary
drivers, but system otherwise works fine, and this huge bug, was
confirmed by many peoples out of which I probably an only one with
nvidia device.)

But, notice, that in 2.6.30-rc, same regression happens, but it isn't
anymore due to ehci (I even copied suspend/resume code from the 'good'
version), thus there is some hope that addtional bisect might reveal
things (and I finally managed to set up distcc properly over wlan, and
get 100% on all systems, well 2 systems, the trick is to use many
threads, something like 15 or so, and I can now do full bisect cycle in
about 10 seconds)
