Well, I've done this on the CCR and the RB1100. In both cases, the
chassis is not directly grounded by the AC cord anyway. Inside the case
is just a switching power supply brick. I never checked whether DC was
grounded beforehand (I probably should have), but I have not added any
ground connection other than the fact that the rack is grounded.
Honestly I've never used the warranty, so I have no qualms about voiding
it :)
I just keep using the wattage from the spec sheet for load calculations.
I couldn't prove whether their DC power supply is more efficient than
mine, so I can't see trying to adjust.

Subject: [AFMUG] converting AC devices to DC
So you guys that are bypassing the internal ac;dc power supplies for
the devices that arent sold DC, are you grounding chassis? and I assume
there is no way to not void your warranty by doing this?
on spec sheets, the current consumption listed im guessing is
accounting for the conversion loss as well, is there a rule of thumb
for calculating your demand (ie 10% or whatnot)
