The fonts are stored in DRAM. The OSD, MPEG2 decoder and the video
buffer have to be in SDRAM. 
Most of the 2MB SDRAM is used by the MPEG2 decoder for decoded pictures
and other data (like buffering B-frames).
The rest is needed for the video and audio buffer.
OSD normally goes into the optional extra 2MB SDRAM, which is not 
present on this card.
Freeing up DRAM will not give us any more space for OSD.
