No work was done on the cirrus driver in a long time.
There seems to be support for the 7548, though. It is possible thsat
forcing the cirrus driver to recognise your card as a 7548 might be
enough to make it work.

You are a few years to late. All datasheets were available from cirrus'
weebsite. Unfortunately, they are not there now, and I did not download
the LCD controllers datasheets.
You idea of porting the code from the X driver to the svgalib driver
should work with no problem.
