I just got the Micron Xceed IIci-128 Cache Card last week. I've only
found a few incompatibilities so far, but the cdev included with the
card makes it easy to shut it off. 
As for speedups, as well as doing memory caching it includes an INIT
which patches the SANE traps for greater speed at a loss of
precision.
For a quick comparison using Speedometer:
				CPU	Math	Disk	Overall
SE 20Mb disk:			1.00	1.00	1.00	1.00
"Standard" IIci 40Mb disk:	5.15	9.79	3.42	5.73
My IIci (see below):		6.28	45.57	2.19	13.32

I just ran this test under MultiFinder (6.1b9) from my Removable
45Mb Hard Disk.  Both the cache and SANE traps were turned on.  As
for percision, doing the Savage test with traps on was ~10^11
vs. ~10^-19 with the traps off.

Hope this gives you the information you want.
