Current version of "bm status" bit test works as long as
no USB device is in use. When USB device is plugged in ACPI
function in this context is always returning 1. Until reboot.
Direct I/O is working fine even when many USB devices are
connected.
Change bm_timeout value to less annoying. 1000 is still much
more then worst case observed and it is much better when status
bit gets stuck.

Remove duplicate multipliers in clock_ratio table. On 1,4GHz
Nehemiah two frequencies are present twice in table. It isn't
fatal, but with voltage scaling enabled each will be set twice.

Longhaul with voltage scaling enabled works great on Ezra
CPU (Longhaul ver. 2). As long as "conservative" governor is
used. Both "ondemand" and "userspace" can change voltage
from min to max at once. Motherboard unfortunatly turns off
when vid difference is big. Longhaul was printing warning
message, but it is not enough. Now driver will have
"conservative" governor built in and will split bigger
changes to smaller ones.

It is good idea to wait for PCI bus to become idle before
frequency change. Thanks to ACPI it is possible. It makes
sense only when northbridge support is in use because it is
only case in which we can disable arbiter after check if PCI
bus is busy.

When the PST tables are broken, powernow-k7 uses ACPI's processor_perflib to
deduce the available frequency multipliers from the _PSS tables.

Upon frequency change, processor_perflib performs some verification on the
frequency (checks that it's within allowable bounds).

powernow-k7 deals with absolute frequencies in KHz, whereas perflib only
deals with MHz values. When performing the above verification, perflib
multiplies the MHz values by 1000 to obtain the KHz value.

We then end up with situations like the following:
 - powernow-k7 multiplies the multiplier by the FSB, and obtains a value
   such as 1266768 KHz
 - perflib belives the same state has frequency of 1266 MHz
 - acpi_processor_ppc_notifier calls cpufreq_verify_within_limits to verify
   that 1266768 is in the allowable range of 0 to 1266000 (i.e. 1266 * 1000)
 - it's not, so that frequency is rejected
 - the maximum CPU frequency is not reachable

This patch solves the problem by rounding up the MHz values stored in perflib's
tables. Additionally it corrects a broken URL.

It also fixes http://bugzilla.kernel.org/show_bug.cgi?id=8255 although this
case is a bit different: the frequencies in the _PSS tables are wildly wrong,
but we get better results if we force ACPI to respect the fsb * multiplier
calculations (even though it seems that the multiplier values aren't entirely
correct either).
