15	  The 2.4 kernel changed the kernel start address from 0x310000
16	  to 0x810000 to make room for the Wildfire's larger SRM console.

20	  If you're using aboot 0.7 or later, the bootloader will examine the
21	  ELF headers to determine where to transfer control. Unfortunately,
22	  most older bootloaders -- APB or MILO -- hardcoded the kernel start
23	  address rather than examining the ELF headers, and the result is a
24	  hard lockup.
