* IDE-drivers supports 44-bit adressing, meaning no more 127GB limit of HDD!
Possible, but this wouldn't be the only change they would make anyway. There would be fundemental changes to the partioning, so we'll see changes in this as well when/if it ACTUALLY happens. The hoaxer also fails to realize it's 137GB limit, not 127GB.... Team Xecutor would not make this mistake.
* Playing originals even if you replace your DVD-drive!
Not going to happen. If they could do this, we'd already see utilities to read Xbox discs in PCs. In fact, this requires a DVD-ROM FIRMWARE CHANGE. It has nothign to do with the Xbox BIOS.
* Support for Wireless LAN with use of USB-adapter! (Tested with Netgear Ma101)
Ummmm... dumb. Lousy guess on the part of the hoaxer. It's easy enough to hook into an external wireless LAN adapter using the ethernet. Why would they bother with a USB based ethernet port??
* SAMBA network share device support!
Blah. This would be a pointless feature at this point, for many, many reasons.
