The screen goes blank (with some green lines at the top part) during the boot and then I get my regular GDM login screen. I am passing  the parameter "video=lxfb:1024x768 at 60" in my GRUB file and I have compiled this into the kernel:

So you are saying that the lxfb boots fine at 800x600 at 60?  Have you tried
any other modes?  Can you switch the mode manually from the command line
with fbset?
