OSL: the bogus event group code appears to be unused aside from the os_EvGrpInit() call in os_Initialize(), so let's table it aside for now, and thus spare the boatload of compiler warnings.

#include "types.h"

void
cmd_dieid()
{
	u32 addr;

	for (addr = 0xFFFEF010; addr <= 0xFFFEF016; addr += 2)
		printf("%08X: %04X\n", addr, *(volatile u16 *)addr);
}
