Motorola's (Well, DSC made the hardware) cell switch was driven by Z-80s until just a few years ago, when the upgrade was made to PPC chips. Of course, the RP-1 ran the Z80 code in emulation mode. Base stations have less computing power than that, but it tends to purpose built hardware. (Linux is unlikely -- (at least) two ofhte bigger infrastructure suppliers are UNIX source licensees.)
