It's likely that the chips which don't support VLAN assist also can't handle VLAN headers in their TX checksumming engine. This is in acenic.c - ACENIC_DO_VLAN is a check to see if 8021q is compiled into the kernel or available as a module.
#if ACENIC_DO_VLAN
dev->features |= NETIF_F_HW_VLAN_TX | NETIF_F_HW_VLAN_RX;
dev->vlan_rx_register = ace_vlan_rx_register;
dev->vlan_rx_kill_vid = ace_vlan_rx_kill_vid;
#endif
