I was waiting the merge of the patch serie from Hannes
Reinecke <hare () suse ! de>, because of the sequencer fixes.
I did'nt try this patch serie myself because the sequencer
fixes one ([PATCH 5/6]] never reach lkml or linux-scsi.

I will compile a clean 2.6.15 today and give it a try this
evening.

Regards,
Emmanuel.
