[parisc-linux] FB on c3k

[grundler@dsl2.external.hp.com (Grant Grundler)]

Getting closer.

I'm comfortable that FB ioctl wrappers are ok with an updated
version of the ioctl32.c patch (ftp.p-l.o:patches/fb_ioctl.diff).
"fbset -v -i" on c3k (64-bit kernel, PDC 4.6, Vis-EG/PCI) reports:

But when I try to "fbi foo.jpg", I get diagonal black "lines" from
top left to bottom right striped about 3-4 pixels wide and spaced about
12-16 pixels apart (all just guesses). Tux does show up in the top
left corner at boot and stays there. System seems to lock up.
TOC doesn't work. Power off occurs 20-30 seconds after hitting power
button.

I suspect some parameter isn't right for FB device definition
but don't know what. Hoping the diagonal lines are the clue
that someone could tell me about - some sort of "off-by-one"
type of error.

thanks,
