/dev/mem is available only for root and like you said it might even be disabled
completely.

`lspci -vvv` also requires root access and doesn't really show anything
interesting aside from the PCI-E link state.

The Linux kernel has no APIs for exporting low-level CPU/GPU information and
Wine developers won't add it either because Windows utilities use their own
drivers, so these APIs will be worthless for Wine applications.
