2.6.11: USB broken on nforce4, ipv6 still broken, centrino speedstep even more broken than in 2.6.10

Linux is getting less and less usable for me. :-(
My new nForce 4 mainboard has 10 or so USB 2.0 outlets. In Windows,
they all work. In Linux, two of them work. Putting my USB stick or
anything else in one of the others produces nothing in Linux.
Apparently no IRQ getting through or something?
This is what /proc/interrupts has to say:
177: 9503618 IO-APIC-level ohci_hcd, eth0
These are the USB boot messages:

As you can see, it appears to work in principle.
Now about IPv6: npush and npoll are two applications I wrote. npush
sends multicast announcements and opens a TCP socket. npoll receives
the multicast announcement and connects to the source IP/port/scope_id
of the announcement. If both are run on the same machine, npoll sees
the link local address of eth0 as source IP, and the interface number of
eth0 as scope_id. So far so good. Trying to connect() however hangs.
Since this has been broken in different ways for as long as I can
remember in Linux, and I keep complaining about it every half a year or
so. Can't someone fix this once and for all? IPv4 checks whether we
are connecting to our own address and reroutes through loopback, why
Finally Centrino SpeedStep.
I have a "Intel(R) Pentium(R) M processor 1.80GHz" in my notebook.
Linux does not support it. This architecture has been out there for
months now, and there even was a patch to support it posted here a in
October last year or so. Linux still does not include it. Until
2.6.11-rc4-bk8 or so, the old patched file from back then still worked.
Now it doesn't. Because some interface changed. Now what? Using a
Centrino notebook without CPU throttling is completely out of the
question. Linux might as well not boot on it at all.
Did I mention that I'm really tired of you putting stones into ATI's
way? You might believe you have a right to piss everyone off, after all
people get what they paid for. Or maybe you think you are on a crusade
to promote open source software. But if you keep alienating me (I'm a
software developer) like this, I spend more time working around this
bullshit and less time writing free software. In the end, everyone
loses. I sincerely hope some day you people are done pissing in the
pool and can create at least some semblance of semi-stable APIs. This
house is never going to be safe for living until you stop digging around
You know, people are actually spending time (and money!) to learn how to
write Linux kernel modules. And all this API shifting makes sure their
knowledge is completely obsolete a few months down the road. That's not
how you create a community of people working on a shared goal.
Enough ranting for today. Sigh.
