Is there any chance that you could connect a serial line to the machine? Your report about blinking keyboard led's means that there's an oops, but since the display isn't in textmode (and the oops obviously happens when trying to enter it), we don't know what it is. A serial line (along with a kernel compiled with serial console support, of course, and a kernel command line option like "console=ttyS0,115400 console=tty0") would get that. You'd just need another machine with a terminal program like minicom.. The network console could also work out, but serial lines tend to be more reliable if you have them. But in the absense of serial lines, see the Documentation/networking/netconsole.txt file for some details. The setup is more complicated, but on the other hand it's a lot more dynamic, and in your case - since the box works until you try to switch to text-mode, I suspect the network console dynamic run-time setup would be easy for you to use. (For other examples of using netconsole with that dynamic mode, just google for "sys/kernel/config/netconsole" and you'll find a number of docs that explain how to find the MAC address for setup etc).
