IIRC the WRTs don't have a sprom, instead its stored in their nvram
flash area:
For a WRT54GS v1.1:
[EMAIL PROTECTED]:~# nvram show | grep -E "^(wl0[^_]|pa0|board|et0|il0)"

An older bcm47xx patch had this part in bcm43xx_main.c to fetch the
values from nvram:
#ifdef CONFIG_BCM947XX
/* In the case some settings are found in nvram, use them
* to override those read from sprom.
*/
c = nvram_get("boardflags2");
if (c)
sprom[BCM43xx_SPROM_BOARDFLAGS2] = simple_strtoul(c, NULL, 0);
c = nvram_get("boardflags");
if (c)
sprom[BCM43xx_SPROM_BOARDFLAGS] = simple_strtoul(c, NULL, 0);
c = nvram_get("il0macaddr");
if (c)
bcm43xx_aton(c, (char *)&(sprom[BCM43xx_SPROM_IL0MACADDR]));
c = nvram_get("et1macaddr");
if (c)
bcm43xx_aton(c, (char *)&(sprom[BCM43xx_SPROM_ET1MACADDR]));
c = nvram_get("pa0b0");
if (c)
sprom[BCM43xx_SPROM_PA0B0] = simple_strtoul(c, NULL, 0);
c = nvram_get("pa0b1");
if (c)
sprom[BCM43xx_SPROM_PA0B1] = simple_strtoul(c, NULL, 0);
c = nvram_get("pa0b2");
if (c)
sprom[BCM43xx_SPROM_PA0B2] = simple_strtoul(c, NULL, 0);
c = nvram_get("pa1b0");
if (c)
sprom[BCM43xx_SPROM_PA1B0] = simple_strtoul(c, NULL, 0);
c = nvram_get("pa1b1");
if (c)
sprom[BCM43xx_SPROM_PA1B1] = simple_strtoul(c, NULL, 0);
c = nvram_get("pa1b2");
if (c)
sprom[BCM43xx_SPROM_PA1B2] = simple_strtoul(c, NULL, 0);
c = nvram_get("boardrev");
if (c)
sprom[BCM43xx_SPROM_BOARDREV] = simple_strtoul(c, NULL, 0);
#endif
