alienware hardware

Dear kernel-people,
Please give me hints
How can I track down next problem: we've got a new laptop from alienware
(Septa model seems to me). We've tried kernels shipped with debian:
2.4.26 and 2.6.6 but then I moved to vanila 2.6.7-bk7
and problem persisted: during boot after some point it becomes way too
slow : like it is running 100MHz, but checking
/proc/acpi/processor/CPU1/* showed that it didn't switch to any
throtelling mode or anything like that. Just it runs the process in "R"
mode on 99.9% cpu utilization user mode:
CPU states: 99.8% user, 0.2% system, 0.0% nice, 0.0% idle
It seems that it slows down right after starting work with IDE... though
I can be wrong. Probably it is linked to the fact that most of the
devices are not recognized by the kernel and it uses some bad defaults?
Also I've tried to specify idebus=66 because it was complaining about
setting default 33 but it didn't quite help...
Here are some detailes about the machine:
