Andreiux said it in one of the SDS threads :
" I also was one of those who said that you don't need the bootloader, because, well you don't really it. It's just a case of having something flashed via download mode where that scenario comes into play. I'm not familiar at all with the internals of the bootloader, so that's why I said it. For daily use the patched kernel and MMC driver is enough.
Personally I didn't use download mode for flashing something in over 7 months, so I couldn't care less about the bootloader driver having the patch."
