'Maintenance Menu' impl.? - bad kernel recovery

[gladx83]

I was wondering if anyone knew how the Maintenance menu was implemented.  Is it part of the kernel, bootloader, etc?  And if I upgrade to a kernel image that won't boot - is totally hosed - will I still be able to access the maintenace menu and flash the ROM.

To put the question another way - is the maintenance menu at all dependent on the kernel thats currently there?

Thanks,
-Brian

as far as I know, maintenance menu is totally independant from your rom/kernel/flashable memory, and it's the best (only) way to unbrick your zaurus after a bad kernel flashing
