Try 'options "MAXMEM=73728"' instead. MAXMEM uses the number of KB, not
MB. 72 * 1024 = 73728. I'm trying the same thing right now with 96MB, and
it'll hopefully work.
One other thing: be sure to recompile *without* the memory, as gcc seems
to have problems if you have more memory in there than is detected. After
you finish building the kernel, power down, put the new memory in, then
power it back up with the new kernel. And be *sure* to save the old
kernel ("mv /kernel /kernel.save") in case things don't work, so you can
at least pull the memory and come back up with the old kernel.
Good luck.
