I took an hour or so break from studying and did some digging into the 871s.

First up you can use a standard 64mb/128mb/(or in my case 256mb double
sided) pc133 cl3 sdram dimm to upgrade the memory from the default 128mb.
 The 128mb dimm only gave me a 64mb boost so i tried the 256mb dimm and got
the maximum amount possible in an 871 series.

Secondly, the flash on the board is only 20mb plus a 4mb strataflash chip
on a card (with decoupling caps, and 3-4 resistor points which are likely
used for id bits).......I think it might be possible to just buy a larger
chip on ebay, and swap them out, possibly with fiddling with the resistor
locations (currently unpopulated) on the board.  I suspect however that
this will destroy the current firmware/flash filesystem on the router so a
serial xmodem transfer is probably required to realize this.  One could
always just try and find a cheap cisco branded card of course.....

Finally, the 871s have an internal mini pci (not mini pci-e!) slot, and if
you have an Atheros ar5212 based wifi card from a circa 2005
dell/acer/whatever laptop, you can do a bit of work in rommon and enable
wireless functionality (albeit a/b/g only).
