BUG (?) in aic7xxx (5.0.18): Doesn't recognize Ultra!

Hello,
I was unable to find the location of the aic7xxx mailing list, so I am
posting my information here. If someone could provide me with the list
server address for the aic7xxx mailing list I'd appreciate it! I can then
provide this report there as well.
I used to use the old version 4 of the aic7xxx scsi driver. However, when
I switched to an experimental kernel (2.1.106) I found that the new
driver, version 5.0.18, does not recognize that my 2940UW is an Ultra SCSI
card.
The board_name is correct but the AHC_ULTRA flag is not set! As a
consequence one of my disks which is an Ultra Wide model is set to 10MHz
transfer rate instead of 20MHz. I haven't seen any reports of this
problem in my web searches. I'm not sure if it is my misconfiguration or
a bug in the driver. Any help would be appreciated!
Here is the relevant portion from my boot log (ver. 5.0.18):

The Quantum Viking should be an Ultra SCSI at 20MHz transfer rate. A
quick look at /proc/scsi/aic7xxx/0 also shows that the ULTRA option is
mising. Please note that the "Adaptec AHA-294X Ultra SCSI host adapter"
string is merely from a table lookup. It does not indicate whether the
driver is in ULTRA mode. If the driver is in ULTRA mode, the word "Ultra'
is printed on the same line as "Wide". Below is the proc info:

Being a hacker, I decided to set the ULTRA flag manually in aic7xxx.c by
adding p->type |= AHC_ULTRA. Of course I shouldn't _have_ to do this but
I tried it out just to see what the result was. This time the card is
recognized as an Ultra SCSI card. However, the Viking drive is still not
setup to transfer at 20MHz! Here are the boot logs and the proc info:

To demonstrate nothing is wrong with my hardware, I have provided below
the boot log and proc info from the old driver. Note that I used the flag
aic7xxx=ultra at boot time of the old kernel. This option seems to be no
longer valid with the new version.

As you can see my Quantum Viking is running nicely at 20.0MHz with the old
driver!
Thanks in advance,
