Nice plugin, needs a few tweaks

Thanks for the nice plugin. A few tweaks would be great:
1. Use standard Nagios warning/critical thresholds
a. ex: check_ibm_bladecenter -H mychassisIP -C public -m powermodules -w 4: -c 3:
b. The above check returns an error, and even when a single digit (i.e. -c 4) is supplied, it doesn’t seem to affect the status. In my environment, 2 power supplies are redundant so I would like to get a warning if 1 drops (4 p/s = OK, 3 p/s = WARNING, 2 p/s = CRITICAL)
2. -m blowers returns first blower twice in status but shows correctly in perfdata
a. OK – Blower1 OK. Blower1 OK. | blower1=60% blower2=61%
