Question on system memory, ultra-5

[Garance A Drosihn]

I have an ultra-5 that I'm using for freebsd/sparc64.
Some lines from dmesg:

   FreeBSD 5.1-BETA #0: Thu May 29 12:41:58 EDT 2003
       root at shine-on.netel.rpi.edu:/usr/obj/usr/src/sys/Ultra10-GAD
   Preloaded elf kernel "/boot/kernel/kernel" at 0xc0440000.
   Timecounter "tick"  frequency 300000000 Hz
   real memory  = 108290048 (103 MB)
   avail memory = 100139008 (95 MB)
   cpu0: Sun Microsystems UltraSparc-IIi Processor (300.00 MHz CPU)

Now, when the system boots up, the initial hardware startup
message claims the machine has 128 meg of memory.  Why does
freebsd think there's only 103 meg?  Could that suggest some
bad memory chips?
