Another framebuffer _device_. :) Namely OFfb, which just uses the

What do you mean by my 'DRM modules'? Beware that my dri-trunk packages
currently don't work very well with an M6.

Define 'flicker'. The current dri-trunk packages would apparently cause
a very low refresh rate. If it's a quick flicker where you see the
picture multiple times OTOH, it could be a radeonfb glitch I'm seeing
with an M7. VT switching helps with that one.

No need, the server has plenty 1024x768 modes built in.

Bottom line: if VT switching doesn't help, you probably don't want to
use my packages just yet. (at least not the latest version, older ones
should work)
