The Thinkpads seem to have a pretty active net community doing sites like
www.thinkwiki.org, which are very helpful. There's nothing bad about Intel
CPUs, actually I consider them the best choice ATM for laptops, especially if
you get a device with an Intel gfx chip inside, they have excellent FLOSS
drivers. Personally I agree that Thinkpads are a bit overpriced, you can get
equivalent laptops cheaper from manufacturers like Acer or MSI, which are the
two companies I have first hand experience with: I have an MSI S260 which
currently gets replaced by an Acer Timeline 3810T. Both are well supported by
Linux. The new one requires bleeding edge software, i.e. Debian unstable in my
case. On the ACER, no interrupts are shared when AHCI is enabled, but I guess,
that's normal for AHCI:
$ cat /proc/interrupts

I didn't yet do any hardcore audio tests on that laptop, it's running an
upstream large latency kernel. With laptops, I think, it's important to know
your ways of using it. For example, the Acer is not the fastest device around
(it's just a single Core CPU), but it's very light (1.65kg) and has an amazing
battery life (up to 8h with dimmed display), so it's great to take on the road
which is where I will be using it the most and where I can deal with a slower
CPU, but not with a huge and heavy monster. The other extreme would be a
netbook, but I prefer the 13" screen of the Acer - my eyes don't cope well with
10" screens, and Atoms just don't cut it in the long run for audio work. So to
me, the Timeline is a good compromise, but your compromise will probably look
different.
Ciao
