He patched his kernel with the IMQ device, which is known to cause all
kinds of weird problems.

Wich problems? Known to whom?
I was considering using imq for our needs (not done yet), and from the
FAQ at http://www.linuximq.net/faq.html (item #3, "Is it stable?") it
seems there's no problems except of gre tunnels and locally generated
traffic...
Googling for "imq linux problem" shows usual pile of various user
support questions (how to configure.. what did I do wrong.. etc),
but nothing relevant.
So... I'm curious whenever the claim on linuximq.net site about the
stability is true, or there in fact are some real issue...
Thanks.

Known to me (who wrote the original implementation of the current IMQ
device) and numerous people who were hit by them. IIRC it does some
invalid skb refcounting hacks which result in crashes in certain
scenarios - but I don't remeber the exact details.

The lartc list had lots of reports of crashes. I guess "imq crash" or
"imq oops" will give better results.

>From what I know these problems haven't been fixed. Current kernels
include Jamal's tc actions and the ifb-Device, which obsolete IMQ
anyway.
