I tried to build a sparc kernel with UVM support and got the following:

law:APOLLO {116} make

`libkern.o' is up to date.
making sure the compat library is up to date...
`libcompat.a' is up to date.

Stop.

I set up the config file like this:

## Virtual memory configuration.  There are two choices, the old Mach
## based VM system, or the new UVM system.  Old VM requires the pager
## options.
#options        OLDVM           # MACH VM
#options         SWAPPAGER       # swap paging
#options         DEVPAGER        # paging to devices
#options         VNODEPAGER      # paging to vnodes
options         UVM             # UVM VM

but there is some strangeness, if I try with the pager options set, like this:

config          netbsd  root on ? type ?

## based VM system, or the new UVM system.  Old VM requires the pager

*** Stop.

Which looks like they are being set elsewhere.

Any thoughts?
