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).
