Broken ata/ad%d.

[Mark Murray]

Hi

After cleaning out some OBE(?) patches, the closest I can get my
Libretto 110CT to booting a really recent CURRENT is terminated
by a panic.

Hand-written backtrace is:

Debugger()
panic()
acpi_read_ivar()
ata_dma_init()
ad_attach()
ata_boot_attach()
run_interrupt_driven_config_hooks()
mi_startup()
begin()

The panic message is "bad ivar read request (6)"
