I have been using a thinkpad z61m. The most problems that I have had
were the graphics, in that it had an ati x1400 display. Now that the
driver is open source, I don't have to deal with the headeaches of
fglrx and realtime. As of the latest distros, I have had no problems
getting anything working. I have never gotten the webcam to work,
though, but I have never had a use for it either.
The Z61m is quite large, definitely not thin and light, but it is
sturdy. The reason I got it initially was due to the fact that it had
firewire built in, while the T series did not. You may be able to get
a deal on a slightly older model of thinkpad as it comes off lease.
Unfortunately, I do not know of a good wholesaler to recommend.
I do not know if the T series have similar interrupts, but I will
post the commands you requested below.

As Frank mentioned, the Thinkwiki has been a wealth of information for me.

__________________________________________
It feels like my several year old PC will crap
out soon for one reason
or another, so I need a replacement, better sooner than later.
This time it should be a laptop and I heard that formerly IBM and now
Lenovo thinkpads are of good build quality, even if they only come
with intel CPUs and cost an arm and a leg.
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:

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
