So I think the problem is that Grub expects the keyboard to be a USB 1.x device when it needs to be USB 2.0. I tried:
# note I forgot the /grub in original submission but you get the idea
Neither the G510 or my generic USB keyboard functioned at this point (presumably because usb_keyboard doesn't talk to the ehci module), but no booting issues occurred either. lsmod showed Grub auto loaded usbms with ehci.
I also spotted Linux registering the G510 as a "full speed USB device" after loading ohci in Grub.
