The DRI+KMS graphics drivers will conflict with framebuffer drivers for the same hardware. The kernel only allows one driver to bind to each PCI device and normally that prevents you from making this mistake. vesafb is an exception because it doesn't bind to a specific PCI device, but you should not expect it to work.

Hmm. Maybe my memory is really going to $@#! due to middle age, but I seem to remember that saner switching between X and VCs was one of the selling points of KMS. But if that means you have to stay in 80x25 for the VCs it's not very persuasive.

By default on my system KMS sets the console framebuffer to 1900x1200, which makes fro a quite high res text console (I don't know how much, but far more than 80x25).

I do wonder how to set the resolution to something nonstandard. As far as
I can tell with Radeon KMS there is no way: the resolution the monitor prefers is always selected. This is normally fine for those of us with LCDs, but for the poor sods stuck on CRTs it seems suboptimal.

LCA: Graphics driver ponies Posted Jan 28, 2010 21:52 UTC (Thu) by michich (subscriber, #17902) [Link] Boot parametervideo=800x600 works for me with Radeon KMS. See Documentation/fb/modedb.txt.

OK, no wonder I couldn't find the docs. fb/modedb.txt is, uh, not the most
obvious of places :)
(though 800x600 is the last-ditch fallback resolution in any case, so

If the text is too small change the console font to something bigger.

You set it through the KMS driver, not vesafb. (But don't ask me how!)
