Here is a patch for packed pixel software imageblit. Since the code to
draw a color image and a mono image are almost the same I merged them.
Second I made the code generic enough to work on big endian and little
endian code at the same time. I set my radeon card in my x86 box to big
endian mode and tested. It worked for me but I like people on big endian
machines to test it. The last fix was to deal with the 16 color logo. The
fb_set_logo was unpacking the 4bpp info. Now cfb_imageblit can handle the
logo data directly. Most hardware expects the data not to be unpacked.
Another bug was image.depth was always set to 8 in fb_show_logo. This is
in correct. Please test. Thank you.

Hi James,

Tested on vesafb: works
Tested on rivafb: crashes on fb_show_logo().
