Black (non-updating) radeon console with CONFIG_FB=m works with CONFIG_FB=y.

I'm having about the same problem as what you are describing.  The
earlier boot uses VGA text, but as soon as it goes to what should be
the framebuffer the screen goes black until X, which displays
normally.  Switching to console from X results into the cursor
vanishing, but the rest of what was on the screen in X continues to
display at what should now be console.  The '*ERROR* invalid
framebuffer id' is being displayed when I'm entering X not when
leaving.

Bret, try compiling the frame buffer into the kernel CONFIG_FB=y as
the frame buffer is only broken for me when it's a module.  I see
Miles has his compiled in, so I'm thinking it's a different bug.

The working CONFIG_FB=y version adds a Console: output message.  That
message comes from drivers/char/vt.c bind_con_driver.  Any reason it
would fail when the frame buffer is compiled as a module?

I tried 2.6.34-rc7 with CONFIG_FB=m and it also gives a non-updating
console.
