The original Linksys WRT routers used MIPS + Linux, but later switched to something (perhaps ARM?) + Palm OS.

If I recall correctly the switch was motivated by a licensing dispute - Linksys used Broadcom wireless chips, and Broadcom wouldn't allow Linksys to release the source code for the Linux kernel modules required to operate the Broadcom chips. As a result Linksys were called out for violating the GPL (I don't know if the dispute ever got to court), and switched from Linux to PalmOS.
