Because this is possibly the first time someone with a Radeon 4850 shows up. New cards are added as needed.
No, there's an entry for the 4800 series. But it's not uncommon for a series to have on the order of 20 PCI IDs associated with it, and we're obviously not going to add all of them.
I'm all for giving people the chance to shoot themselves in the foot, or other body parts, if they so desire, but please don't file bug reports with such configurations.
