I don't see, technically, why would couldn't put them in line.

I've included two half-ascii'd schematics, with example subnets.

[ Internet ]<--ISP Feed-->[ m0n0wall ]<-->[netgear]<-->Cisco Switch


[ Internet ]<--ISP Feed-->[ netgear ]<-->[ m0n0wall ]<-->Cisco Switch

Given the relative security of both devices, you're going to run into 
far more configuration and troubleshooting issues than the security that 
two inline firewalls will give you (in other words, you're hedging your 
bets that someone will be able to break into the first firewall but not 
the second, at the expense of a network that's a tad more complex)

You might, at the worsst, have to do NAT'ing twice.  At the best, you'd 
only have to NAT at the ISP facing firewall and route the 
network to the second firewall.
