Same sort of problem here, with a Mitac 8170 - P4 2Ghz with 512 of RAM with
latest bios..
I made some investigation and it seems like vista is really more fastidious
on acpi than olders windows..
I look at the DSDT ACPI Tables of my own computer, andI got no real error,
juste only some minor warnings, and nothings that should make visat claim
that the computer is not ACPI compliant...
May be there is something wrong with the ACPI Check...
Some more informations about checking ACPI :

The more suprisly is that I got an older PC (an HP Paviliion with an really
old Althon 1Ghz, that have more error in ACPI and Vista boot without
complain...)
Does someone know a way to contact more directly the ms team about vista ?
I will really be happy to help for improving vista on laptops (or others
hardware..)
