The Ubuntu beta doesn't work for me

[Lubos Pintes]

Hi all,
I tried the Ubuntu beta Live CD yesterday on my Asus A6Rp AP050. It 
doesn't work:
- I cannot switch to console for starting brltty (I don't have USB one).
- The Alt+F2 doesn't work. I think that nothing works at all. Too bad I 
haven't some experienced person who would tell me what is happening 
precisely.
- It seems that only thing I can do is to restart it and instead of 
restarting it freezes :-D.
- I tried acpi=off of course. (I must do it for Ubuntu and in general 
any kernel to boot)
Note that I have the 7.04 working so something in beta is broken.
