>Description:

        On a Sun Netra T1 model 200 (500 MHz UltraSPARC IIe),
        NetBSD 5's spdmem(4) driver reports the RAM as:

        spdmem0 at iic0 addr 0x54
        spdmem0: SDRAM memory, data ECC, 133MHz (PC-1100)
        spdmem0: 13 rows, 11 cols, 11 banks, 4 banks/chip, 7.5ns cycle time
        spdmem0: tAA-tRCD-tRP-tRAS: 3-20-20-45
        spdmem0: voltage LvTTL (not 5V tolerant), refresh time 7.8us 
(self-refreshing)

        This system in fact uses PC-133 SDRAM, not PC-1100.

        This problem also manifests on the Sun Fire V120 which is
        a speed-bumped version of the samee motherboard.

>How-To-Repeat:
        Boot a NetBSD 5 kernel
        read the autoconf output
        note the mismatch between NetBSD reported RAM type, and actual RAM type.
