F16 beta TC1 garbled graphical screen

[Jurgen Kramer]

When I get past the current dracut/squashfs problems (BZ#735199)
(workaround maxcpus=1 works for me). I only get a garbled graphical
screen so I cannot continue with the installation.
anaconda textmode is no longer there and xdriver=vesa gives the same
garbled screen.

All F16 alpha rc's and alpha worked fine with the graphical installer.
Did something change here?

btw this is when booting through EFI. Legacy boot works.
