I would need a suitable category to try to add the ADSL cards I have to h-node.

Once this category is added I may test if this functions properly with a FSF endorsed operating system by confirming if it connects to the ADSL service or not.

My current card is the Traverse Technologies Solos PCI ADSL2+

I have a 2 port variant, it appears in lspci -nnv as follows:

04:08.0 ATM network controller [0203]: Xilinx Corporation Device [10ee:0300]
	Flags: bus master, medium devsel, latency 32, IRQ 20
	Memory at 90118000 (32-bit, non-prefetchable) [size=128]
	Memory at 90110000 (32-bit, non-prefetchable) [size=32K]
	Kernel driver in use: solos
	Kernel modules: solos-pci

It replaced a Sangoma S518 card that had only proprietary drivers available from Traverse (openadsl) and Sangoma (wanpipe) to operate it.

That appeared in lspci -nnv as:

04:04.0 Network controller [0280]: Globespan Semiconductor Inc. Pulsar [PCI ADSL Card] [14bc:d002] (rev 01)
        Subsystem: Globespan Semiconductor Inc. Device [14bc:0018]
        Flags: stepping, slow devsel, IRQ 7
        Memory at fc000000 (32-bit, non-prefetchable) [disabled] [size=64K]
        Capabilities: [40] Power Management version 2
