Lee,
I know this is far from easy... but, What do we need to do this? I haven't seen such a cooler feature in a Thinkpad like the HDAPS. (Well, maybe the fingerprint reader) But, how can we / I help, if this is ever done?
Please see:

I have discovered several previously unknown emu10k1 hardware features using this procedure to reverse engineer the Windows drivers, including a per channel half loop interrupt, and added support to the Linux driver for some of them.
It may be much easier to find the read and write register subroutines than in the above guide. The Windows driver I was working with had exactly one subroutine that used the inb, inl, inw, outb, outw, outl instructions, so it was trivial to set breakpoints to log all the port I/O. I later found it was even easier, the version of SoftIce I was using allows you to set I/O breakpoints, so all you need to start logging the register activity is the port.
I had a little trouble loading the IDA symbols into SoftICE at first, just because the first few scripts I found on the net didn't work.
Some devices use memory mapped IO, I have no idea how you would RE these. Maybe someone else has some pointers?

The only thing I got back from IBM was:

I don't think I'm l33t enough like to call there and discuss for what we are looking for. Also they will probably tell me, " Ahh, well we currenly don't want to release anything because of legal issue" (Like I was already told)
