When I asked Transmeta about PPC and 68k support, they said nothing about the PPC but said that 68k was totally possible, it would just take some one towrite the microcode. It would even be possible to have 68k and x86 running at the same time!!!
when you contacted them, did they just talk about the possibilities, or eventually of planning to do sth. like m68k microcode ?! :-)
btw : ppc is (imho) not possible, because of the totally different technical specs.
