This is a pretty good setup guide for the TP 600E.  I have only a few

With the current mwave driver you can't choose an IRQ that is the same 
as the disabled IR.  So the above will work fine, but say if for some 
crazy reason you want to have the serial port use 3 and the mwave use 4, 
you will get a bogus message from the mwave driver about a conflict with 
the IR, even though the IR is disabled.  I have a patch for this.

In Debian one must recompile the kernel to get the mwave driver, but the 
support files are installed with a simple "apt-get install mwavem" .  A 
Debian user might also want to install the tpctl, thinkpad-base, and 
thinkpad-source packages maintained by Thomas Hood.

One should use the number that your ThinkPad displays during bootup.  I 
have nominally 160MB and my 600E displays 163264k.  Without this kernel 
boot parameter your ThinkPad will eventually crash when both the 
firmware and Linux try to use the same memory.

When I used a 16-bit pcmcia network card it would want to steal the IRQ 
from the modem, but now that I use a 32-bit cardbus network card it 
leaves the modem and serial port IRQs alone.

It looks like a couple of lines got chopped off above.  There are 
several ways to configure the sound, depending on whether you use the 
OSS, old ALSA, or new ALSA driver.  The above looks like old ALSA.  In 
the archives of this list and on several helpful web pages you can find 
working examples of all three setups.

Doesn't Mandrake have a nice kernel compile helper like Debian's 
make-kpkg?  Can one use "make dep;make rpm" to build a kernel package? 
 One should probably use the .config used by your distribution's kernel 
as a starting point.  You might find that in /boot.
