Not sure if this helps, but some modules seem to accept debug_level 
parameter at load. In GPL tarbal for W8980 (http://www.tp-
link.com/resources/gpl/GPL_TD-W8980.tar.gz) i found this line:
#insmod /lib/modules/drv_dsl_cpe_api.ko debug_level=3
Also, there are references in code to this: 
https://github.com/xdarklight/lib_ifxos/search?q=debug_level

Also, using binwalk, I was able to extract dsl firmware from latest 
W9980 firmware update (TD-W9980_V1_150507).

filename: xcpe_574306_571801.bin
version: 5.7.4.3.0.6-5.7.1.8.0.1
sha1sum: f8a13f16f5ead64bb0d2d551fbef8f1a838322f7
filesize: 923152
Firmware1:
        PLATFORM: 5
        PLATFORM_STR: VRX200
        APPLICATION_TYPE: 6
        APPLICATION_TYPE_STR: VDSL over IDSN
        VERSION_STR: 7.4.3
        RELEASE_STATUS: 0
        RELEASE_STATUS_STR: Release
Firmware2:
        PLATFORM: 5
        PLATFORM_STR: VRX200
        APPLICATION_TYPE: 1
        APPLICATION_TYPE_STR: ADSL Annex A
        VERSION_STR: 7.1.8
        RELEASE_STATUS: 0
        RELEASE_STATUS_STR: Release

Might be useful as it seems to be newest version reported so far.
