I've had no trouble booting any of the recent kernels on my T41, but I'm 
still stuck on 2.6.9-1.681_FC3 because subsequent kernels all freeze on 
resume from APM suspend and ACPI suspend consumes battery power at the 
same rate as when the machine is powered up.  Haven't tried the USB or 
sound features of recent kernels.

Any other TP users noticed these issues?

More on the OP's note below.

You might try starting in runlevel 3 and running "system-config-display 
--reconfig".  Also, check /var/log/Xorg.log.  Which display do you have?

Not surprising.  Once the machine locks, it won't react to anything.  This 
is what I see on APM resume.

Firefox does crash from time to time--that's not T41-specific.  X still 
crashes occasionally when running 3D screensavers (also not T41-specific), 
but I don't run screensavers on my laptop.  I haven't tried VMware on the 
recent kernels either.  On the older kernel, VMware sometimes causes hangs 
when shutting the host down, but it hasn't caused any panics for me. 
Don't know about more recent kernels.

lm_sensors shouldn't make any difference on Thinkpads any more, but it 
can't hurt to have it off.  On the other hand, turning it off hasn't 
prevented any of the problems I described.
