Checkin 464bdd33e9baad9806c7adbd8dfc37081a55f27e "fbdev: ignore VESA
modes if framebuffer is disabled" is just plain wrong on any system
which has support for extended text modes in its VESA BIOS.

Antonio is incorrectly assuming this branchout is used only to set VESA
graphics modes, but it's to set any VESA mode, be it text or graphics.

I wonder if this fbdev update is what causes my X session to die?

I'm using the VESA driver on my ATI R580, and just filed this bug report 
minutes ago: http://lkml.org/lkml/2007/5/8/667

Perhaps, but not due to this partiular patch. :)

Not that particular patch, but yeah, it could certainly be the fbdev 
update.

Can you try bisecting it?

I did, however, take a cue from this and the setup rewrite now makes the
VESA graphics mode unselectable if CONFIG_FB is off.

That's doubtful though, CONFIG_FB=n. For a start, you can try reverting
changes in drivers/char/vt.c and drivers/video/console/vgacon.c
