I can confirm that problem for my fe41z.
After upgrading from 7.10 to Alpha 5 my system wasn't bootable anymore. Rec. mode worked.
Live CD from Alpha 6 couldn't boot. And the Beta LiveCD has now exactly the problem which is described above.
I can't check the debug patch, because I need that PC for work ;)
