Loopy has been working on his DS firmware patch, and we just did a test run. The patch, with the clever name of FlashMe, works perfectly for the testers so far. It boots DS homebrew automatically if it detects it (hold select to override) in about 0.1 seconds. Expect a public release soon.
For those scared of connecting the sl1 bridge we have good news, it will stop flashing if you don't short properly, and it will continue automatically when you re-bridge it. Do NOT, however, turn of your DS before it says patching is done, that will brickify your DS.
FlashMe can be run from Passme, or from WifiMe. After the flash you do not need these methods to boot homebrew, of course.
