Yes, two drives per physical PDC20269 card. 

> Are all four drives running in DMA mode?

Yes, all are running udma6. Here's what hdparm tells me for all drives
(only difference is serial number):

# hdparm /dev/hde

/dev/hde:
 multcount    =  0 (off)
 IO_support   =  0 (default 16-bit)
 unmaskirq    =  0 (off)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 30515/255/63, sectors = 490234752, start = 0
# hdparm -i /dev/hde

/dev/hde:

 Model=Maxtor 6B250R0, FwRev=BAH41BM0, SerialNo=<...>
 Config={ Fixed }
 RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57
 BuffType=DualPortCache, BuffSize=16384kB, MaxMultSect=16, MultSect=off
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455
 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio1 pio2 pio3 pio4 
 DMA modes:  mdma0 mdma1 mdma2 
 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 
 AdvancedPM=yes: disabled (255) WriteCache=enabled
 Drive conforms to: (null): 

 * signifies the current active mode

Interesting, I will try them out ASAP and return to you!
