Bug was introduced as kernel #9397 (http://bugzilla.kernel.org/show_bug.cgi?id=9397) on 2007-11-16 10:53 At least kernel 2.6.26.3 from kernel.org works again, thus the bug was resolved. Debian Kernel 2.6.24-1-686 still has the bug. The actual default testing kernel 2.6.26-1 does not have sata_sis configured (CONFIG_SATA_SIS is not set) and thus does not work on my system at all; however just enabling CONFIG_SATA_SIS works.
