Thanks for the tip. Not only does it work on Ultra5 with Linux-2.4.18, but you have to do it only once! After the first remount, I can mount the file-system rw as a normal user, but can write only as root - due to the different UID/GID mappings on the SunOS UFS partition and the Linux ext3 partitions - which is fine, I think.
