Around line 1297 of drivers/dahdi/wctdm.c you could change:

 if (wctdm_getreg(wc, card, 1) & 0x80)
                /* ProSLIC 3215, not a 3210 */
                wc->flags[card] |= FLAG_3215;

 to

 wc->flags[card] |= FLAG_3215;

and just skip the read of register 1. I don't know if this will work in your
case, but it's something to try.
