[Acer Aspire One] Resolution 1024x600 not avaiable booting into text mode

Hi ppl

I’m running opensuse 11.3 on my new Acer Aspire One, with a 10.1 inches monitor and a screen resolution up to 1024x600.
I don’t know why I can’t set that resolution when I boot in “Failsafe Mode”; the highest one I can choose is 800x600 (0x314).

Obviously, booting with runlevel 5 into gui mode I can set that resolution and everything works fine.

Any ideas?
