Hello Mark,

I know not all the P4's are HT capable. The slowest P4 w/ HT is, from what
I know, the 2.4, which is what I have. The 'ht' flag is present, however
I'm not as sure as I was yesterday that it represents HT capability, since
I saw a 2Ghz P4 with the flag what is not HT capable.

Here is an output of lshw regarding my proc, maybe you guys can notice
more than I can:

 *-cpu

also reiser4 wasn't patching properly on hardened and i was bored of

you're right about the chip:

Anything that cane be done about this?

I've added a couple of more modules to see if it helps, if anything
changes I'll post it.

I did run sensors-detect, and it did discover another module, however that
is for my tvtuner (eeprom).

I will look for the w83627hf on the board, however from your description
it sounds very familiary, so it's probably there.

I'll check out the IRC channel and/or the mailing list tonight after I get
home.

Thank you for all your information and help!
