/dev/mem exists for example, but you are still not supposed to go

* Super-I/O chips at 0x2e/0x2f and 0x4e/0x4f.
* Legacy PC hardware monitoring chips at 0x290-0x297.
* IPMI interface at 0x0ca3 and 0x0cab (read-only).
Please tell me which ones should be skipped on PowerPC.
Skip the whole thing. I consider that on a powerpc linux port, the
