...concerns about the quality of the random data from most drivers resulted in their contributions from the pool being removed.

This was also changed recently: all IRQs now contribute to the random pool, but with very little entropy credited (something like 1 bit per 64 IRQs).

Hurrah! This is better. The timer interrupt on modern systems can produce something indistinguishable from random given a high enough precision time source. Of course, you don't actually know it's random so you can't credit it, but it will definitely help the generation of unpredictable numbers on otherwise quiet systems.
