I'd appreciate it if anyone who has been having cardbus trouble,
solved or not, could try again with the following.  In particular, if
you needed to set RBUS_MIN_START, please have a look at the heuristic
code and see if the value I put in works for you; setting
RBUS_MIN_START will disable the heuristic and do what you said.

This probably ought to get pulled up to netbsd-4, but I'd like some
broader experience and more reports before I request that; I only have
Thinkpads.

	src/share/man/man4: cardbus.4
	src/sys/arch/i386/i386: machdep.c rbus_machdep.c
	src/sys/arch/i386/include: rbus_machdep.h

Log Message:
Add a heuristic to set rbus_min_start based on total RAM.  The new
behavior is to choose 0.5 GB for <= 192 MB, 1 GB normally, and 2 GB
for >= 1 GB.  This should make the defaults work additionally old
Thinkpad 600Es, and also on notebooks with lots of RAM (e.g. T60 with
2GB).
