linux.config: add pegasus USB driver

actually, dm9601.c should be the right driver for
idVendor=07a6, idProduct=8515 == ADMtek ADM8515:

drivers/net/usb/dm9601.c:
USB_DEVICE(0x0a46, 0x8515),    /* ADMtek ADM8515 USB NIC */

however, the vendor id there is either a typo, or ADMtek uses
2 different vendor ids. this remains to be investigated.

the pegasus driver works though for the device.
