Yes I am.

2.6.31 --> instant reboot. Not one line of printk on the screen.
35d5a9a61490bf39d2e48d7f499c8c801a39ebe9 and 'lower' --> Get a 16 16MB env 
which didn't boot.

I got clued up and booted with init=/bin/bash, so for the fingered commit 
(i.e. the one switching from all-happy e820 to bios-88), I managed to 
remount / rw and capture dmesg.

Not sure how that interacts with earlyprintk=vga though. Did I get everyting 
there is to get?
