There is a HP SLIC in the ACPITBL.bin module which is INCOMPLETE. Even though you see that it is useless. The SLIC that is added as 'nocompress' 0+2 method is HP SLIC 2.1 I don't see an issue since you have activated Vista. Once WIN7 is out and if there are issues report back and we can take a look at this again. Hope this helps.
