OnTrack Technology's Miniscribe Disk Manager, v3.6, has a little BIOS extender
program that patches your BIOS to allow more than 1024 cylinders.  I installed
a 3180 in a 386 with an ESDI controller, using Disk Manager, and it works
very well.  I can't say much for the amount of RAM it takes up, but... ya
gotta take the good with the bad, I suppose. :-)
