So far my device has been stable at 800 MHz, and the boost given for any CPU-bound task is very nice. After getting used to this it would probably suck to go back to 600

One has to remember though that even if the device runs stable, it's lifetime could get seriously reduced due to increased thermal stress. So those users who were worrying about their N900s getting obsolete probably don't need to apply...
Depending on the actual ceiling of the chipset, the actual degradation curve of the silicon is not proportional, so if you stay under the point / ceiling, the chipset should last a normal life. Based on most Droid efforts, the "comfort" zone appears to be 800 mhz, but most report no problems at 900mhz or 1ghz. All kinds of issues are reported at 1.2ghz and this is the point temps spike by ten degrees.

Depending on the cooling system in the N900 compared to the Droid, the N900 should last as long at 800mhz as 600mhz (for a max speed with dynamic clocking). Seems the N900 has better heat dissipation (based on tear-down views of both).

The point that the actual ceiling is breached, the temps will spike about ten degress and freezing will occur. This is the point and state that the chipset will have a much shorter life span. Unless for whatever reason, the 3430 in the Droid is a more robust / better version.
