No, I use the sonypi driver. But I can test the sony-laptop one as
soon as it is in -mm again if it would be of any help.

Ok, now I feel totally dumb. 's2ram -s -f' actually works iff you disable
fb support completely in the kernel. It works even from X. Don't know how
many combinations I tried but that one somehow slipped through. Anyway
thanks for your help. So could this machine be added to the s2ram

Thanks,
