Hmm, that's a newer version than I am familiar with. Apparently in
more recent versions, the tool is requiring a width be specified for
unnamed registers and/or registers for which the width is unknown.
That being the case, append the width specifier .B (one byte) to the
register address. For example:

# setpci -s 2:0.0 0xf0.B

HTH,
Bruce.
