I've got this working nicely now. I have a

monitor via the matrox card. Nice!

I've just done a bk pull from linus and build a new
kernel (was using post rc2 
before) and now this nice scheme (see above) fails
to work:

When I 'startx', the X log complains about no core
keyboard, my usb keyboard 
stops responding and both screens go blank. I can
only get access by ssh from 
another machine.

Nothing changed other than kernel; using same
.config.

If I boot on rivafb console instead of matroxfb,
startx and keyboard work 
fine.

Before I start hunting down the problem; Do any
recent changes spring to mind?

-rc3 is bug-fix only, so no, I can't think of any changes in fbdev/fbcon
that will cause your problem, unless someone submitted changes without
passing through this list.

Anyway, here's linus' changelog between rc2 and rc3.

  o fbdev: Fix for using >16 pixel wide font in fb console*** 
  o fbdev: Support for bigger than 16x32 fonts in softcursor
  o fbdev: Support for bigger than 16x32 fonts in rivafb cursor
  o fbcon: Disable fbcon cursor if vt softcursor is enabled***
  o fbdev: Allow mode change even if EDID block is not found
  o fbdev: Fix cursor in doublescan mode in atyfb
  o fbdev: Fix typo in atyfb
  o fbdev: Change the find_mode behavior***
  o rivafb: fix broken burst length calculation
  o fbdev: Fix screen corruption in neofb
  o fbdev: Fix lockup when switching to/from X/console
  o fbdev: Fix module_param in rivafb
  o fbdev: Fix crash if fb_set_var() called before register_framebuffer()***
  o fbdev: fix wrong colors at 16 bpp in tridentfb

*** affects core fbcon/fbdev layer
