Since sym(4) provides a super-set of trm(4) and we have recent-ish reports of sym(4) working, it makes sense to trim this driver from the tree. The specific cards it supports aren't all that popular, the couple-extra features that trm(4) gave over sym(4) aren't really that relevant today, and it's been years since trm has had good testing and maintenance.
