are using an old unconverted driver. Most (if not all) of the drivers
for common hardware are newbus these days. However, we don't want
to encourage people to take the easy way out and write new drivers
using the shims. This is just passive "encouragement".

Some controllers submit bogus pointers to the Done queue.
ohci_hash_find_td fails to find these in its hash and panics. Instead of
panicing we now assume the whole done queue is lost and let the timeout
code to clean up the mess after us.
condition.
- 1 line change that allows to balance chips between ncr
and sym using pci compat option (not compiled by default
in 4.0 but maintains the driver source 3.4 compatible).
uhci_check_intr() routine needs to be more careful about deciding when
the end of a transfer has been detected.
This allows me to remove the nasty workaround code from if_aue and if_cue.
Receive performance is now much better for these adapters (500KB/sec
vs. 350KB/sec).
Also removed unused KUE_CUTOFF define from if_kuereg.h.

Try to support older systems reporting irq0 for the first channels.
Support sharing of the std interrupts (says peter :) )
Dont use READ_CD on normal data reads (2048 bytes), too many old drives
doesn't support this command even if the std says "shall" :(, but still
use READ_CD on all other blocksizes.
Add the geometry to the ad probe, its still usefull.
does ignore DCD. Even TIOCMGET cannot read DCD as the firmware doesn't
report it. This has pretty interesting effects for ppp(8) which runs
in clocal mode and polls carrier (!). (Specialix's linux driver does
this too)
Also update the firmware to 3.0.6 for the SX cards, as apparently there
was a problem with floating (disconnected) DCD pins causing stray carrier
transitions, especially at port open time.
It seems to work here, and carrier loss is detected nearly immediately
rather than having to wait for a LQR timeout (a few minutes) before ppp(8)
gives up.

Dont be so verbose in the probe, only ONE line printed now, to get more
info boot verbose. Centralise most printf's in ata-all & ata-dma to use
the ata_printf function, it saves alot of codelines.
Repeat the identify command if drive fails the first.
Protect the timeout functions with splbio.
Dont update the transfer details before we are sure the transfer
succeded, this way they are proberly retried on errors.
Move the handling of next_writeable to userland.
Use the READ_CD command to read CD's. That enables us to read _anything_
via the normal read/write interface. This kindof obsoletes the READAUDIO
ioctl, but we keep that for now.
