Subject: Voyager Video support color depths?

Everyone,

I had a question about the various video support that has been tested with
the 2.4.25 DENX Kernel.

To date I have had pretty good luck with by making sure I have compiled the
kernel with the Voyager.h file set at 32 BPP mode.

For speed optimization I wanted to cut it back to 16 BPP mode, however I
couldn't hardly get it to boot the machine after I did this change by
changing '#define SCREEN_BPP 16'. Most attempts the kernel would lock up
before a login prompt was available. When I tried SCREEN_BPP at 8 then it
booted fine, however QT/Embedded had terrible colors.

I was wondering if I should be looking for the trouble in some other code,
or perhaps hardware, or if this is a known bug in the SM501 / Voyager
driver, or perhaps the linux frame buffer driver.

Thanks all,

-Russ
