maybe a practical way, eat the pudding and fake a make until error brake?
example (untested):

$ dd if=/dev/zero of=/pathtomountfilesys/dumbig bs=256M count=1 seek=8192

$ dd if=/dev/zero of=/pathtomountfilesys/dumbig bs=128M count=1 seek=8192

$ dd if=/dev/zero of=/pathtomountfilesys/dumbig bs=32M count=1 seek=8192

Maybe chose a smaller block (that may speed up the actual writing but
would slow down the seek time) say:

$ dd if=/dev/zero of=/pathtomountfilesys/dumbig bs=1M count=1 seek=2222000

no time nor place here for a real test so if anyone around there
has a pinch off each he'll may report if that's practical or not ;-)
