The OIDs you described obviously return space in semi-megabytes.
First thing to do is to let MRTG know you don't want the real thing
but rather the 1024 bytes per kilo variant.  If memory serves well,
this is "Kilo[target]: 1024" (but do check this in the docs).

Then, you need to tweak MRTG so that it knows about the "M".
Normally, MRTG works with bytes, not megabytes. Either multiple
the incoming value by 1024*1024 or alter the kMG values to
display alternative prefixes (so your "kMB" would become "GB").
In essence this tells MRTG that you already have "mega"s and if
you do it right, all prefixes will be okay.  Again if memory
serves well:
"kMG[Target]: M,G,T,P,E" together with "ShortLegend[Target]: B"
This would display "MB" where MRTG would normally display "B",
"GB" where normally "kB" and so on.

cheers,
