This allows one to select the method of 3.3V card detection from the
three possible choices (none (0), the "6710 way" (1) and the "6729
way" (2)). The default is the 6710 way, since it works in the most
cases. The datasheets for the 6722 suggest that the '29 way is more
correct, but experience has shown this method to cause some laptops to
hang solid. See source code for details until I update the man page.

o It needs to have pcic_isa_intr intrrupt handler
o for pci interrupts, in the func interrupt handler it needs to check the isa
registers rather than the pci ones for card present.
o better commentary for some of the strangeness of the 6729 on pci
o fix some crunchy comments to better reflect reality.
With this I almost have the WL200 working, but an interrupt storm
after attach is causing problems for reasons unknown. This code
doesn't seem to break the normal clpd6729 case, and I'd like others
with 6729 cards to try to test it (there were some that were used for
external pccard slots in pci only systems).
card behind it (without the pcmcia form factor). This entry gets to
the point of attaching, but there's something wrong with the '29
support, so it doesn't quite work yet.
while. This is only the script pieces, the glue for the build comes next.

o Use VM_ALLOC_WIRED within Alpha's pmap_growkernel(). Also, because
Alpha's pmap_growkernel() calls vm_page_alloc() from within a critical
section, specify VM_ALLOC_INTERRUPT instead of VM_ALLOC_SYSTEM. (Only
VM_ALLOC_INTERRUPT is implemented entirely with a spin mutex.)
o Assert that the page queues mutex is held in vm_page_wire()
on Alpha, just like the other platforms.
so it needs an explicit #include <machine/frame.h> to get 'struct
trapframe'. The fact that it needs this at this level is rather bogus
but it will not compile without it.

on the Itanium2 system I have when we use up *all* of the initial 256MB
direct mapped region before we are ready to dynamically expand it.
The machine that I have has 4 cpus and a very big hole in the middle.
This makes the bogus '(last_address - first_address) / PAGE_SIZE'
calculations especially dangerous and caused many millions of initial
PV/PTE's to be preallocated.
o "struct addrinfo" contains a pointer to "struct sockaddr,"
not "struct sockaddr" itself
o the function takes a pointer to "struct in*_addr", not to
"struct sockaddr," so the address length must be corresponding

o Add preliminary support for Cirrus Logic CL-PD6729 using PCI
interrupts. To use it you you need to set hw.pcic.pd6729_intr_path
to 2. This is allow us to still default to ISA intrrupt path for
this part (which is found much more often in laptops using ISA IRQs).
But some PCI cards have this part on them and this should allow them
to be used. It is untested on PCI, but it seems to not break the ISA
case.
o Better sysctl descriptions (I hope).
