can a machine running linuxbios be remotely reset/reboot from crashed/frozen state over a network connection?
This needs dedicated hardware in the machine and LinuxBIOS is "just" software. Also, LinuxBIOS is done and over with in the system after it has started the payload.
If your (server-class) machine has a networked IPMI BMC then you can do remote reset with it just as well if the machine runs LinuxBIOS as it would with the vendor BIOS. Well it *should* work, who knows :-)
