Direct Memory Access seems to be enabled:

# hdparm -v /dev/hda
/dev/hda:
multcount    =  8 (on)
I/O support  =  0 (default 16-bit)
unmaskirq    =  0 (off)
using_dma    =  1 (on)
keepsettings =  0 (off)
nowerr       =  0 (off)
readonly     =  0 (off)
readahead    =  8 (on)
geometry     = 624/128/63, sectors = 5033952, start = 0
busstate     =  1 (on)

I didn't use any compiler options:

./configure
make
make check
su
make install

# bogofilter -V
bogofilter version 0.92.6
