Data has been sent in another e-mail.

Unfortunately, I was off-line doing these tests (because I can't
connect to the company intranet :-P), so I did't see your e-mail.
I'll be able to reboot and collect this information later, but there's
Real Work I have to get done at this point....  I can tell you that in
my working configuration, both with 2.6.37 and with the latest Linus
tip with commit c4ff4b829e reverted, I have no interrupt assigned to
the TPM.

See above; I can get this information later, if it's really needed,
but unfortunately it's on the company laptop, and I have some real
work I need to get back to.  (I don't need network access while at

done and I have to get back to coding.  :-)
