if you look at drivers/mips.cpp you'll find the nvram layout

/*

	 *
	 *   Offset  Length  Variable
	 *    0x0e      4    netaddr
	 *    0x12      1    lbaud

	 *    0x14     20    bootfile
	 *    0x28      1    bootmode
	 *    0x29      1    console
	 *    0x2a      1    ponmask? or something similar
	 *    0x2b      3    unused?
