After rebooting and doing one more test, I got this when
running /sbin/rmmod dvb_ttpci:

Nov 22 13:21:35 vdr2 kernel: saa7146: unregister extension 'dvb'.
Nov 22 13:21:35 vdr2 kernel: PANIC: double fault, gdt at c2015000 [255 bytes]
Nov 22 13:21:35 vdr2 kernel: double fault, tss at c2017780
Nov 22 13:21:35 vdr2 kernel: eip = f7881416, esp = bf88921e
Nov 22 13:21:35 vdr2 kernel: eax = f7881408, ebx = f6df6cc8, ecx = f7401a7f, edx = f788144d
Nov 22 13:21:35 vdr2 kernel: esi = f7881409, edi = f79231c1

Looks like the S2API driver isn't in a state where it can actually be used, yet...
