There're a couple of known problems in booting the latest mmotm, 
2009-09-14-01-57, on T60p.

The first is passing a NULL pointer to a workqueue from 
clocksource_mark_unstable().  This is fixed by reverting 7285dd7 
"clocksource: Resolve cpu hotplug dead lock with TSC unstable" from the 
x86 timers/core tree; Martin's fix had no affect on this crash.

 [ I notice Thomas has since provided patches for this problem, so I'll 
   check if it solves this issue on T60p. ]

The second is an issue with the i8042 driver's laptop table not being NULL 
terminated.  This is fixed by Jin Dongming's patch at
http://marc.info/?l=linux-kernel&m=125263897713267.

The config you attached, however, is very different from 
mmotm-2009-09-14-01-57, so perhaps try this kernel with the above two 
fixes to see if you can successfully boot?
