pm3fb: Preliminary 2.4 to 2.6 port
This is a basic port from 2.4 kernel to 2.6. Acceleration is lost and big endian support probably too. The driver works in 8, 16 and 32 bit mode. [adaplas] - change VESA_* to FB_BLANK_* constants - removed unused function clear_memory - fix uninitialized variable compiler warning - some whitespace cleaning [akpm@linux-foundation.org: Nuke pestiferous CVS string] Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
