The answer is: yes there is a way. First prize goes to Casper Dik
<casper@Holland.Sun.COM>. I'll quote his message in full:

Other solutions were:
Use tunefs afterwards to reduce minfree:

mayank@mss.mss.com (Mayank Gupta)
Install on a scratch disk and copy over to the real install disk after making
filesystems with the right parameters:
