It's been improving, but as of 2.4.20-pre7-ac3, I'm still having problems. The card is in a 33Mhz slot on a Micronics W6LI board. When I write to the drive (hdg, seen as scsi ID 0) with cdrecord, it will write successfully for some time (usually 30 MB or more, sometimes even completing a write), whereas in older kernels it would fail between 1-4 MB. The only log message I get is ide_scsi: scatter/gather table too small, padding with zeroes. and about 10 seconds later the system hangs. Related to this is that after this happens and I restart the machine, the PDC20268 drivers will report timeouts resetting the card, and the only way to regain control of the CD-R is to power the machine down. (I will send this in a seperate message).
