Test drivers and test hardware with zero enumeration can use below 4G
addresses just fine.
Also, debugging is not an issue and some non-default kernel or boot
option can enable any sort of device i guess, so my main worry isnt
really security but that we should stand in the way of the apparent
practice of *shipping* user-space drivers that use /dev/mem ...
Thanks,
Ingo
