Re: Shopping for low-power ARM firewall SBC

I am looking for a low-power, preferrably-pc104-form-factor (or thereabouts) dual ethernet SBC type of ARM board with a CF slot for building a custom NetBSD firewall thingy.

http://www.embeddedsys.com/subpages/products/sbc1625.shtml looks like a great match (although I am not sure it will run NetBSD out of the box; the CPU looks like it's supported, and it comes with RedBoot) but it turned out to be prohibitively expensive in single units.

I've also been looking at http://www.embeddedarm.com/products/board-detail.php?product=TS-7300 which really has more features than I need, but a more attractive price. However, it doesn't have CF unless you buy a pc104 addon separately, but then the form factors differ. It only does SD, and I'm not sure it's even possible to support it in NetBSD (it ships as a blob driver in Lignux IIUC).
I've since released the source of that binary-blob SD driver. The guts of the SD access are abstracted in a OS-independent sdcore2.c API with api calls sdreset(), sdread(), and sdwrite(). ftp://ftp.embeddedARM.com/ts-arm-sbc/ts-7500/sources/sdcore2.c

I did successfully write a SD card driver using this source back in 2006 (before we released sdcore2.c openly) on a TS-7260, but I've since lost it.
I really do wish we had better NetBSD support for all our boards.
