Yes.  However, it's not as simple as it is with RPM-based
distributions.  I've been hacking on this to make it simpler, but it's
not there yet.

First, install the libsmbios-bin package, which is in sarge at least.

Run getSystemId (as root) to get the System ID.

# getSystemId
Libsmbios:    0.13.6
System ID:    0x01A8
Service Tag:  XXXXXXX
Express Service Code: XXXXXXXXXXXX
Product Name: Precision WorkStation 380
BIOS Version: A07
Vendor:       Dell Inc.
Is Dell:      1

The interesting value here is the System ID.
Now you've got to manually download the right BIOS payload file from
for your system.  In my case that is the bios.hdr file in the
directory.  (See, my system has BIOS A07, but there's A09 available).

Now that it's downloaded, you can:

# modprobe dell_rbu
# dellBiosUpdate -u -f bios.hdr
(read what it says. If no errors, reboot.)
