The increase of size is due to the updated lmodern fonts.

It occurs only with lmodern fonts (recompiling the same files with 
fourier produces output files of comparable sizes with TL2004 and 
TL2005). Actually, the lm*.pfb files are bigger this year:
lmr10.pfb has grown from 77410 to 106666 bytes for instance.

Quality has to be paid in terms of file size, I guess...
