The 2100s is supported, I have it running with no problems at least on many
machines. It is however a pain in the neck and I recommend against any
adaaptec products.

On slackware 7.1/8.0 I did the following:

Booted from cdrom.
insmod adaptec.o from a floppy disk (on the disk I had insmod static and
the adaptec.o 2100s module I downloaded from the Suse site.)
this the recognised the controller.
I tried fdisk /dev/sda it reported no disk. 
wait 10 seconds.
try fdisk /dev/sda again it works. 
then partition and format manually, there were no problems with this. 

Alternatively, later kernels 2.4 have the adaptec controller which 
can be compiled into the kernel without the insmod rubbish.

That approach worked even easier.
