Thanks to Bastian Löher from GSI Darmstadt for following input:
The Version 2.13-5 driver for the sis1100 can be compiled for kernel 3.0.0-12 (Ubuntu 11.10) by altering line 31 of the Makefile:
-ifneq (,$(findstring 2.6.,$(KERNVER)))
+ifneq (,$(findstring 3.0.,$(KERNVER)))
A driver release with a clean solution will be made available beginning of 2012
