I ported the OpenBSD stuff:
alipm*  at pci?
iic*    at alipm?
spdmem* at iic?
admtemp* at iic?

alipm0 at pci1 dev 3 function 0: 74KHz clock
iic0 at alipm0: I2C bus
admtemp0 at iic0 addr 0x18: max1617
spdmem0 at iic0 addr 0x54
spdmem0: SDRAM memory, data ECC, 256MB, 133MHz, PC-1100
spdmem0: 12 rows, 11 cols, 1 banks, 4 banks/chip, 7.5ns cycle time
spdmem0: voltage LvTTL (not 5V tolerant), refresh time 15.625us 
(self-refreshing)
spdmem1 at iic0 addr 0x55
spdmem1: SDRAM memory, data ECC, 256MB, 133MHz, PC-1100
spdmem1: 12 rows, 11 cols, 1 banks, 4 banks/chip, 7.5ns cycle time
spdmem1: voltage LvTTL (not 5V tolerant), refresh time 15.625us

[jkunz@Kriggle jkunz]$ envstat     
               Current  CritMax  CritMin  CritCap     Unit
[admtemp0]
  internal:     33.000                                degC
  external:     54.000                                degC

This is fine so far. I can't commit the code at the moment due to extensions to 
the MI iic(9) interface. More on that topic later on
tech-kern.
