[MPlayer-dev-eng] mga_vid memory detection error

Hi,

yes, i know... the chip on 16m and 32m models is teh same.. so no way to
make difference unless i write/read verify the memory (matroxfb does that).

hmm

in the first versions i uded this as memory size -------^^^ badly as you can
see, so i've changed it to use chip configuration register flags as the docs
said. also bad...

i wonder where is that 16Mb above comes from...
