Link Aggregation -- will it work for my server?

Well, this puzzled me quite a bit, so I figured that I'd ask around these parts and see if any answers sprawl up.

My server has 3 Network interfaces; A PCI Linksys 802.11g WLAN card, a Linksys EtherFast 10/100 PCI LAN card (Model: LNE100TX), and an integrated 10/100 VIA Ethernet chip. Currently, I have the following setup:

VIA Ethernet Chip: 192.168.0.253

Linksys PCI WLAN: 192.168.0.252

Linksys Etherfast: non-used, awaiting Link Aggregation confirmation

I want to Trunk the VIA Integrated chip and the Linksys Etherfast through my router under DD-WRT v24-sp1 firmware, which supports trunking for ports 3 & 4. This would help me loads for my big stuff, 200Mb/s will definitely not go to waste over here. It would handle (as the lone VIA 100Mb/s chip is doing) both my CoD4 servers, teamspeak, web, etc -- all things big and [mostly] related to external/business usage. Right now, I have all my file sharing going through the WLAN card, ie. my music, file storage, etc for my local home network. That would not change, I'd just need the extra 100Mb/s for the big stuff.

All things networking go through either Cat5e or Cat6 (Cat5e only being used for PS2 and Xbox360 gaming, Cat6 used for everything else).

The server runs XP Pro (required for gaming software I use), and I'd like to see if any of you know of a way to install Link Aggregation/Trunking through XP's NAT configuration for devices, or of any software that can do it externally (ie, a standalone app)

I await your responses!
