cruft weakens the error handling too much for this case.
- weaken the partition entry checking to allow the following treatments
of C/H/S addresses when C should be >= 1024:

(2) allow C to be correct modulo 1024.
Other compatibilty cruft weakens the error handling to allow all

- distinguish primary partition table from extended partition tables.

properly from the beginning:
1) The `kern_devconf' struct should be a part of the driver's
`softc' structure (now it is).
2) The `description' should say what the device actually is,
rather than just giving a model number (now it does).
3) The device should be registered even if the probe fails, so
that it can be reconfigured later.
4) For netifs, the device state should follow the IFF_UP flag.
Other network interfaces should follow this example. (Please?) Eventually
there should be a rundown routine doing the equivalent of setting IFF_UP
off, and perhaps more if warranted.

Use %p for pointers in error messages.
Don't clobber the FPU state when there is an FPU exception. Just clear
the exception flags (after saving the flags as before). This allows
debuggers and SIGFPE handlers to look at the full exception state.
SIGFPE handlers should normally return via longjmp(), which restores a
good FPU state (as before). Returning from a SIGFPE handler may leave
the FPU in the wrong state (as before).
Clear the busy latch _after_ clearing the exception flags so that there
is less chance of getting a bogus h/w interrupt for a control operation.

SCSI driver for FreeBSD. I started from the 2.0R version and mostly
rewrote it. New features are:
1) New probe algorithm. Old driver read the BIOS region of the adapter
memory and find the copyright string. The problem was in the BIOS itself:
it conflicted with IDE disks. The solution was to unplug it and
make the probe algorithm to work without it.
2) Proper timeout handling in numerous places where the driver
polls waiting for some event.
3) Assembler flagments added in critical places, mostly for data transfer
to of from the target. It was possible to make it faster,
but at the price of decreasing reliability.
4) Target-dependent delays when waiting for REQ deassert event.
Some devices seem to be slower (CD-ROMS, some tape drives),
and some seem to be too fast (disks). The driver tests the REQ
deassert timeout for each target and then uses it for polling.
5) Device flags added for SCSI parity control and sense request
priority control.
6) Generic cleanup, after which the driver became much more readable
(at least by me:).
7) Target data parity error logging is limited to avoid log file overflow.
8) Manual page added.
