Doh, so it's only needed for kinetic systems?  I wonder what the table looks 
like without the memfix patch (IE if we could detect if the patch was there 
and work with or without, then again the PRM's document what it's meant to 
provide...)

It's the default in !BtRiscBSD, as there are a few bits that may need looking 
at with BtRiscBSD it might be a case of changing the default string...

possibly, my thinking was to get more of the same modes but different refresh 
rates.

Yes the modes are based on a mode definition file (from a Taxan I believe)

It would be an useful feature to add (the reason being that the real kernels 
on the CD I did were gzipped, the install ones weren't, and the ones that are 
downloaded are normally gzipped as well.)
