The problem lies in the uart attachment, FreeBSD kernel needs some glue 
code to attach sio(4) driver to the minipci card serial ports.

If the image has been built with phk's NTPns archives, NTPNS kernel 
configuration file should already include puc(4), the glue code for 
sio(4) pci attachment.

It may be necessary to add support for the minipci card you bought in 
/usr/src/sys/dev/puc/pucdata.c (pciconf -lv should give the required 
information).

I'm afraid I can't help more ATM, I'm facing an issue when trying to 
build a ntpns NanoBSD image on both 6.3-RELEASE & 7.4-RELEASE FreeBSD 
boxes. ntpns linking fails with undefined references to math functions 
in libphk.

Hope to solve these issues and bring back my spare 4501 to life as a ntp 
server...
