IIRC they do but I'd have to peruse the warehouse at work to see what 
specifically will do this.  The first things that come to mind:

* A PIX something - the PIX 520 (a PII PC in a 4U rackmount booting a 
custom firmware) and PIX 515 (1U rackmount, dual integrated ethernet? 
with 2 PCI slots) are examples I most commonly see
* Anything running IOS capable of having multiple ethernet interfaces, 
as in:
   4000 series
   2600 series
   1750
   1605

For a PC-based solution there's Coyote Linux and LRP (and a couple 
others I'm sure), both of which are "distributions" aimed at firewalls 
running with only a floppy or bootable CD.  Pray you don't ever need 
more than 2 ethernet ports :)

There's also the FreeBSD, umm, "variant" PicoBSD, but I don't know if 
the kernel is compiled with firewall support.  'tis been a while since I 
looked at it.

I'm not aware of any "floppy firewalls" based off [Net|Open]BSD.
