"block-char-major-8" should be "block-major-8", or, more
correctly, "scsi_hostadapter". Since you did not define
"block-major-8", modprobe used its built-in default definition of
"block-major-8" which is "sd_mod".

I have submitted a change to Marcin Dalecki (the author of
modprobe) that replaces these undocumented built-in defaults with a
standard /etc/conf.modules file, which will make modprobe's expected
behavior more visible, although part of my reason for submitting that
change was because I had to extend the data structure modprobe uses in
enabling it to handle multiple aliases (e.g., "alias scsi_hostapter
ncr53c8xx ppa"), which made such initialization a tiny bit more
