AMD's Cool'n'Quiet support is supposed to be natively built into Vista
(no need for drivers). However, they are finding that C'n'Q setups
that were working fine under XP, no longer work under Vista. People
have been waiting for BIOS updates for their motherboards, and some
have found that the BIOS updates don't fix the problem.
Anyways, it was all a bit mysterious, but it looks like a bit of light
is finally being shown on it: it's Microsoft's fault. The Vole has
very quietly dropped support for ACPI 1.0 tables in BIOS, without
letting anyone know. The ACPI tables are queried by the OS to see if a
particular CPU has support for power management or not. So even with a
BIOS update, they may have still kept ACPI 1.0 tables, and Vista
simply and quietly ignores it. ACPI 1.0 was good enough for XP, so I
have no idea why it's not good enough for Vista.
This just goes to highlight why secretive organizations like Microsoft
should not be trusted. They do stupid random things and people have no
way of finding out what's going on. On Linux, this is not likely to
happen because they wouldn't be stupid enough to drop support for ACPI
1.0 tables -- they'd add support for the newer ACPI versions, but
they'd retain older support too. And if somebody dropped support for
something, somebody else could go into the source code and discover
the problem and fix it again.
