When establishing the ACPI SCI, make sure it's always active low (as well

as level-triggered). Do this by changing the MP config entry that was
set up for the interrupt. Do not change anything if there was an ACPI
interrupt source override, assume that this contains the correct
information already.

Pass pointers to frames from assembly, do not use the 'frame on stack
...
as argument passed by value' trick, as gcc 3.3.x makes (valid) assumptions
about the stack that will not be true. Costs 2 instructions per trap/syscall
on i386, 4 per interrupt for MP. One instruction per trap/syscall on amd64,
2 per interrupt for MP. I expect gcc 3.3.1 to make up for this by better
optimization (it'd better..)
While here, make amd64 compile again by using subr_mbr_disk.c

A few ISA sound drivers like to share dma channels, and hence deferred
...
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.
To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.
All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.
