Well if it's the missing B8G8R8X8 stuff this could be added trivially to the
table like so:
[ MESA_FORMAT_B8G8R8X8_UNORM ] = { RADEON_TXFORMAT_ARGB8888, 0 },
[ MESA_FORMAT_X8R8G8B8_UNORM ] = { RADEON_TXFORMAT_ARGB8888, 0 },

Other than that, I really don't see anything which could make a difference on
le systems.
