Voyager GX color mapping

[Clemens Koller <clemens.koller@anagramm.de>]

Hello, again,

well, my version of the Silicon Motion SM501 driver works now
quite well on the PowerMac (after some data integrity problems
with the card having in a dusty PCI slot. :-(( )

Only one thing is missing: The color mapping in the
32bit mode doesn't fit with X. The fb memory map has a BGRA
color mapping but X11 writes it in RGBA.

I have tried to change the fb_var_screeninfo.fb_bitfield
values in the driver and via fbset -rgba ... but it seems as
X doesn't care at all.

Where do I need to tweak to get it working?
Is there a performance penalty to remap the pixels in software?
Which is the optimum way to get correct color mapping?

Thank you in advance,

Clemens Koller
