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
The sis1100.ko can be built successfully with linux kernel “3.2.0”. But the device files cannot be created automatically while executing “modprobe sis1100”. The files are created automatically under linux kernel “2.6.39”.
