If the dot clock is low enough ( NOT in this case for my board ) you can put the entry even in the 16bpp and 32bpp sec- tions.
The /etc/Xaccel.ini will look something like this

Board = "s3/764-2.xqa";
Monitor = "mfreq/mfreq64.vda";
Depth = 8;

You can check your conversion by running the vgaset program with no parameters while running the Xinside server: it will output an XFree-like line and, if everything went OK, this line will be equal to the line you started from ( except if b and c are equal, I haven't been able to reproduce this situation in Xinside: the best case was c=b+1 ).
