BTW Not all relevant patches were posted to linux-fbdev and me (i.e.
"[PATCH 05/33] fbdev/sa1100fb: Remove dead code") - I found them on
other mailing lists but it requires some additional work from me to
find / process them. If possible please Cc: linux-fbdev & me on all
patches in the patchset. Thanks!
