The best of which is probably to _get_ a TRNG device.
I can recommend this excellent and inexpensive (< £40) one: http://www.entropykey.co.uk/
It will do ~32kbit/s (well, at least that's what mine is doing right now). It is designed for Linux and also for safe use and safe distribution of entropy. It is a small USB device, and uses the USB cdc_acm driver to talk to a FLOSS userspace application (MIT license).
As any USB device, it is _not_ going to be capable of providing entropy to the kernel boot process or to very early userspace.
