Add support for MODEX 320x240x256color with "unchained" adressing, giving
access to all 256K on all VGA's, those with that much memory that is :)
Also make sysmouse use the right resolution in graphics modes.
found by taking my HP800CT apart, perusing HPs (Very good!) service
manual and inference from a bad gif file I found in Finland.
Sigh... But it's a nice machine :-)
accommodate the expanded name, the ICMP types bitmap has been
reduced from 256 bits to 32.
A recompile of kernel and user level ipfw is required.
To be merged into 2.2 after a brief period in -current.

certain variants of the NCR chip from FE_CACHE_SET: FE_CLSE (enable
cache-line size register) and FE_ERMP (enable read-multiple). They
will be re-enabled, if a fix for the underlying problem (a restriction
in the memory to memory move logic of some chips) has been implemented.
This code was eliminated when the PEND_INTS algorithm was added. But it was
discovered that PEND_INTS only worsen latency for FAST_INTR() routines,
which can't be marked pending.

enough and can cause some strange performance problems. Specifically, at
or near startup time is when the problem is worst. To reproduce
the problem, run "lat_syscall stat" from the alpha lmbench code right
after bootup. A positive side effect of this mod is that the name
cache can be set to grow again by sysctl. A noticable positive
performance impact is realized due to a larger namecache being available
as needed (or tuned.)
code. According to the crash dump, bpref is set to 445
and cgp->cg_nclusterblks is 444. Hence in the for loop,
the test fails immediately but the following failure check
(got == cgp->cg_nclusterblks) doesn't trigger because got >
cgp->cg_nclusterblks. This wreaks havoc in the code after that.
Fix: Move one source bit to the left :-)

keep ahold of buffers, and therefore leave filesystems dirty. I haven't
been able to test, but the code compiles. Those who run -current, please
test and report back!!! (Sorry :-)).
