[PATCH for 2.4.x] rivafb & small 16 bit mode problem

[Paweł Goleniowski]

I have already send this once before Xmas but it probably got lost, so I'm 
sending it again:

There is a problem with 16 bit mode with rivafb. Colors are sometimes broken 
(specialy under Midnight Commander). This small patch fixes it. I've been 
using it for last months and it works without any problems.
