Can this be reproduced with linux-2.6.15 from kernel.org,
or is this failure specific to Ubuntu?

Did any ACPI-enabled Linux ever boot properly on this sytem?
If yes, please attach the output from dmesg -s64000 and
a copy of /proc/interrupts from the most recent one that works.
Also, please attach the output from lspci -vv

Please attach the /proc/interrupts and dmesg -s64000 output
from the failure. (the dmesg above is missing its beginning).

The dmesg fragment above does hold a clue, however:

ACPI: PCI interrupt for device 0000:00:1f.2 disabled

I would not expect to see this unless pci_disable_device() were
called for the device, and I would not expect to see that during boot.

ps. can you change the Summary line to something more specific, like:

irq 11: nobody cared - unless pci=noacpi - Toshiba TECRA A4

while you're at it, it would be good to know if "acpi=noirq" is
a sufficient workaround, or of "pci=noacpi" is really necessary.
