Interesting. http://processorfinder.intel.com/scripts/list.asp?ProcFam=826
shows that this has a 400MHz FSB. speedstep_get_processor_frequency()
doesn't support that, so that *could* be it. Although that should have
triggered this message..

    if (!fsb)
	        printk(KERN_DEBUG "speedstep-lib: couldn't detect FSB speed. Please send an e-mail to <linux@brodo.de>\n");

Very odd.

Might be useful, though right now, my bets are on an unknown FSB.
