Getting drivers added to firmware

I'm trying to use a device that needs the cdc_acm driver, but it doesn't appear to be included in the latest Mk V image. How do we go about requesting that it be added? Do we need to make a bug report as a feature request?

Here is the device working on different linux machine (kernel 2.6.32). It is a 2x16 character LCD display that emulates a USB Serial converter:

T: Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.01 Cls=02(comm.) Sub=00 Prot=00 MxPS=32 #Cfgs= 1
P: Vendor=239a ProdID=0001 Rev= 1.00
S: Product=Adafruit Industries
C:* #Ifs= 2 Cfg#= 1 Atr=c0 MxPwr=100mA
I:* If#= 0 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01 Driver=cdc_acm
E: Ad=82(I) Atr=03(Int.) MxPS= 8 Ivl=64ms
I:* If#= 1 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=cdc_acm
E: Ad=03(O) Atr=02(Bulk) MxPS= 32 Ivl=0ms
E: Ad=84(I) Atr=02(Bulk) MxPS= 32 Ivl=0ms

# lsmod | grep cdc_acm

cdc_acm 21862 0

Other WRT images may have it under a slightly different name (according to http://dd-wrt.com/wiki/index.php/USB):

kmod-usb-acm -- Kernel modules for USB ACM (Abstract Control Model) support

acm.o (Modem (CDC ACM) support)

I am also hoping to use the HID driver:

hid.o (Human Interface Device (full HID) support w/ /dev/hiddev raw HID device support)

So I can plug in game controllers and control the Pineapple without lugging a keyboard and monitor around.

Ok, so nevermind I guess. Can someone tell me if I screwed myself by doing what I did?

I was looking through the installed packages with opkg, noticed there may be a package for the kernel module I needed. So I checked the url that opkg uses, which ends up at

http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/packages/

So I pull down the kmod-usb-acm driver, and it wants an updated kernel. I pull down kernel 3.3.8-1, and install them both. Re-plug my device, and I get a ttyACM0 device, and it works!
