No character outside of Gohan has ever gained these kinds of rage boosts (without transforming as a result). When Bulma was killed in the Boo arc, Vegeta didn't get as mad lol.
I'm not sure the situations are entirely comparable. In Cell, they all went to the battle expecting to die. Although the precise circumstances shocked Vegeta enough to boost him, it wasn't that weird in the context of the battle. And again, although Vegeta was starting to get a heart at this point, I think it was more startling to him to have feelings for anyone at all at that point.
By the time Bulma died in the buu arc, everyone on Earth had already died, pretty much. Even Vegeta was dead! Vegeta was expecting to go to hell at this point and never see Bulma again.
In BoG, Bulma is just having a party, and is a non-combatant. I think this is one of those things like, it just dind't enter his mind that was even a possibility. I'm more baffled at how *Bulma didn't die* from that slap, by all accounts she should have shattered, than I am from Vegeta having a comparable power level to Goku -- which is entirely reasonable, in my mind.
