Phone [Q] Installing custom rom, on galaxy s gt-i9000, with a busted power button

Hi there i am relatively new to android modding and rooting etc. I recently tried to install Cyanogenmod to my phone and I succeeded, but the next day my phone began to restart itself, turns out that the power button is broken. We tried to repair it but ended up burning down the processors internal i/o (latch or whatever structure it has) with a faulty multimeter . Now i have to turn on my phone with a dock cable (with 1kohm res) which wakes up the phone, i can access the Download mode by plugging in the dock, and pressing home+down, but the recovery needs the power button signal too.

I can access the recovery by using adb commands, but i need to boot in. If i install a new recovery like CWM, i am stuck in a bootloop and i don't know if i can use the adb commands. Is there any other way to get into recovery mode, besides home+power+up, or adb commands?
Can i install CM onto the phone under these circumstances?

Thanks for any help given!
