you don't increase the number of new dimens, except by using pdfetex
rather than pdftex.  knuth's sets of registers have fixed cardinality
of 256, but etex and omega extend them.

it _is_ the fault of supp-mis; however, it can't help it, since you've
loaded stuff before it (that you're being all coy about) that has
gobbled up almost all the dimen registers.

if one of those things is pictex, see
