    Well, loops_per_jiffy is actually being measured correctly as we're
    using the acpi pm timesource to time udelay(). However there is a loss
    of resolution using the slower time source, so udelay(1) might take
    longer then 1 us.

    If that is going to cause problems, then we'll need to pull out the
    use-pmtmr-for-delay_pmtmr patch. I guess our only option is then to use
    the TSC for delay_pmtrm() (as a loop based delay fails in other cases).
    I'll write that up and send it your way, Andrew.
