Yes, the memory test is slow.  I always set the eeprom "memtest"
variable to 4MB so I don't wait so long for memory tests.  Then,
if I get suspicious of the RAM, just boot in diagnostic mode to
test the remaining RAM.

Leaving the memtest permanently at 4MB also means you have less
chance of running out of EEPROM write cycles (which are limited).
