So you actually want to create random polynomials of degree m ?
Just do
random(B*x^m) where m is the degree and B the bound on the coefficients, e.g.

? random(1000*x^10)
%1 = 546*x^10+713*x^9+887*x^8+998*x^7+729*x^6+768*x^5+595*x^4+368*x^3+832*x^2+419*x+737
? random(1000*x^10)
%2 = 158*x^10+31*x^9+224*x^8+293*x^7+478*x^6+225*x^5+53*x^4+120*x^3+374*x^2+588*x+555

Cheers,
Bill.
