Not really. You may want to give pommed a try, though.

IMAO: yes

No. The scaling governors all pretty much assume intel.

I have this stupid perl script running, but it's less than ideal:

-----
#!/usr/bin/perl

use strict;
use warnings;

my $uptime;
my $one;
my $five;
my $fifteen;
my $tmp;

open GOV, ">/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor";
print GOV "userspace";
close GOV;
open SPEED, ">/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed";
$tmp=select SPEED;
$|=1;
select $tmp;

# Go daemon
close STDIN;
close STDOUT;
close STDERR;
chdir "/";
if(fork()) {
	exit;
}

while(1) {
	$uptime=`uptime`;
	if($uptime=~/^.*age: ([^,]*),([^,]*),(.*)$/) {
		$one=$1;
		$five=$2;
		$fifteen=$3;
	}
	if($one > 0.75) {
		print SPEED "1333333";
	} elsif ($five < 0.75) {
		print SPEED "666666";
	}
	sleep 10;
}
