Trancy released a new version of XBR-Flash. With LFlash it was already possible to update your XBReboot on NAND-16mb consoles directly from your Xbox 360 booted into a Linux Distro like Gentoo (so no need to flash over LPT or USB again). Based on LFlash, XBR-Flash however will now allow you to flash on 256/512mb consoles as well and comes with more additional features.

WARNING: Do not flash your NAND directly from the USB Drive, because the Linux USB driver has a bug and freeze after a while. Copy all needed Data from USB Drive to Desktop and flash from there!
USE THIS SOFTWARE AT OWN RISK.
