I have been using a Soekris Net5501-70 box since June 2008 with a CF 
card running FreeBSD 7.

This is being used for DNS, DHCP, NNTP, network firewall and a small 
asterisk server

I have turned off writing messages to logs, and in June this year, I 
started using an MD for /var/db/dhcpd (as that was getting written to a 
fair amount)
Im still on my original CF card, and as of yet, have not seen any 
problems (touch wood)...

Its not the fastest box in the world, but it certainly does what I want 
it to do. Just takes a long time compiling a world and kernel

Just another option for you...
