'nvapeek' might be something like "nvidia peek(read)"
and
'nvapoke' might be something like "nvidia poke(write)",
MMIO regs.

Addresses 'e114'&'e118' with their 'values' should fall into this range:
- G80:GF100 MMIO map
  0x00e000     all     PNVIO     GPIOs, I2C buses, PWM fan control, and oth=
er
external devices
OR
- GF100+ MMIO map
  0x00e000     all     PNVIO     GPIOs, I2C buses, PWM fan control, and oth=
er
external devices

How Martin reached the actual addresses and values, he knows better. :)
