a4fcac54a1 Fixed a null pointer panic for dumpon(8) on a nonexistent device whose 
driver uses the new disk layer.

47351d2774 Update the ata driver to take more advantage of newbus, this 
was needed to make attach/detach of devices work, which is
needed for the PCCARD support.
(PCCARD support is still not working though, more to come on that)

Support the CMD646 chip which is used on many alphas, sadly only
in WDMA2 mode, as the silicon is broken beyond belief for UDMA modes.

Lots of cosmetic fixes here and there.

Sorry for the size of this megapatchfromhell but it was not
possible otherwise...

newbus patches based on work from: dfr (Doug Rabson)

dc722a14c7 In some drivers we use two devices to be able to boot. 
So if si_iosize_max is allready set, dont mess with it..

Also just log the problem with maxphys not being set once.

46a706dc69 Test the slices for openness before we close them; doing it the other way 
around meant that the higher level close routine never gets called.
(phk is on the road; this is a quick fix to get things working and may need
 more polish)
