The TP600s require some special hacks to get going. I have a 600E that I 
put 6.1 on a couple of weeks ago and needed to do the following:

1. Update to the latest BIOS and embedded controller firmware.
2. Boot into DOS with the PS2.EXE tool and disable all of the devices you 
aren't using. Make sure at least 3 IRQs are assigned to PCI (I have 9, 10, 
and 11 assigned). 
3. Add 'hw.cbb.memory=0xd8000' to /boot/loader.conf.

Boot with that and it should work even with ACPI.

If you search around you might find a suggestion to add a bunch of 
hw.pci.link type loader.conf tunables. I haven't found this to be 
necessary if there are sufficient resources available.

The only casualty appears to be sound, but I can live without that.
