> Interesting. So you don't have the simplefb output that you had before ?

I do now, after a 'make clean' and "make bzImage'.

In between, I had tried CONFIG_SYSFB_SIMPLEFB=n .  That "works", by
falling back to vesafb in every case.  I restored the .config before
testing the patch, but there must have been leftover dregs in the
build tree.  1024x768x32 is garbled, others are good whether simplefb
or vesafb.
