Subject: matroxfb returning incorrect fix.smem_len?

While doing some work on the pci-rework branch of X.org, I noticed
something strange.  matroxfb correctly detects that my card has 16MiB,
but fix.smem_len is only 8MiB.

I looked around the matroxfb code and some of the other driver's code,
and I believe that matroxfb is incorrectly setting fix.smem_len.
Matroxfb sets fix.smem_len to (total_memory_size -
memory_used_by_current_mode).  Other drivers, such as nvidiafb do not do
this.

If folks agree that matroxfb is in error, I'll submit a patch.
