Endianness problems with Xwsfb on radeonfb

[Marco Trillo <marcotrillo%gmail.com@localhost>]

Hi all,

X worked fine with the 'wsfb' kernel driver using the 'ofb' or 'genfb'
kernel drivers. I tried to enable the 'radeonfb' kernel driver, in
order to get a 24 bpp framebuffer in X instead of the 8 bpp mode that
OF sets by default.

It works, but there seem to be some endianness-related problems:

  - when hardware cursor acceleration is enabled, the cursors are
displayed in the wrong endianness. For example the 'X' cursor looks
like '<>' on screen.

  - colors look funny: the red and green channels are swapped, and
there is no blue. It looks like some sort of ARGB->BGRA endianness
problem.

The system is NetBSD 4.0.1, with the standard xfree X sets.
