From looking at the driver. Yes it can. But I don't have a neomagic
chipset to test.
I have a chipset, if someone can can give me pointers to what to look at.
I wont be able to look for a week or two, since the hard disk on the
laptop has died, and needs to be replaced.

Due to the neomagic driver having different use of NeoFbMapSize, here's
a new followup.

I've actually already done it, but I'll probably leave it till after XFree86 4.4.0. Once 4.4.0 is out, I'll merge that into the DRI CVS and create a branch for this work I've been doing on the radeon with regard to dynamic allocation the DRI. Alan.
