With Ubuntu 10.04, the system accepts "ifconfig eth1 mtu N" for any
value of N up to 9000, and shows an MTU of N in response to 'ifconfig'.

With 8.1-RELEASE (not 8.0 as stated before, sorry), the command
'ifconfig bge0 mtu 8000' produces an error:

ifconfig: ioctl (set mtu): Invalid argument

Same thing with 'mtu 1500', 'mtu 1400', etc.
